Skydel Becomes First GNSS Simulator to Break

High-Capacity Barrier

Orolia, a Safran Electronics & Defense

company, has announced that Skydel,

its flagship GNSS simulation engine

software, can generate more than 500

signals from a single platform. By leveraging

its software-defined architecture, Skydel’s

potential can be massively scaled upwards

when employing a robust set of hardware

components. GNSS users, experts, and

manufacturers, as well as those looking

for an LEO-capable simulation system, can

greatly benefit from this unmatched number

of signals.

“GNSS chipset, cellular handset, and GNSS

receiver manufacturers have been looking

for a robust solution that can generate a

very high capacity of signals — with all the

constellations and multiple frequencies –

from a single workstation. Skydel gives them

that capability,” explained Pierre-Marie Le

Veel, Orolia’s Simulation Product Director.

“With the right hardware, Skydel is the first

high-capacity GNSS simulator on the market

that can also accurately generate advanced

multi-path, jamming, spoofing, or the high

number of signals and frequencies needed

for a true LEO constellation simulation.”

Sercel and AP Sensing are pleased

to announce the launch of a joint

innovative solution for comprehensive

railway infrastructure monitoring.The world’s

first Below Ballast Scan (BBS) solution is

the result of joint technical work combining

AP Sensing’s unique Distributed Acoustic

Sensing (DAS) technology and Sercel’s

comprehensive geophysical solution for nearsurface

evaluation using DAS data. The joint

solution provides insights to help customers

understand the roadbed and underlying

geology to better manage their geotechnical

risks.

The BBS monitoring solution provides critical

data needed for safe railway operations and is

an important complement to existing shallow

near-surface inspection techniques and rail

Orolia’s Skydel Simulation Engine offers the

best of both worlds|image: Orolia

Skydel contains a rich feature set that

includes multi-constellation/multi-frequency

signal generation, remote control from userdefined

scripts, and integrated interference

generation. However, one of Skydel’s

greatest assets is its open, software-defined

architecture.

“Skydel’s software-defined GNSS simulation

approach is just the tip of the iceberg,” added

Le Veel. “With more and more customers

simulating multi-path and jamming scenarios,

and the need for more signals in more

applications –even beyond traditional

simulators – the need for high-capacity has

never been greater. The Skydel engine opens

the possibility for users to escalate to over

1000 signals and not be limited by hardware

design.”

monitoring. The use of already-existing fiber

optic infrastructure, together with extremely

long-range evaluation capability, makes the

joint Sercel and AP Sensing solution very costeffective

and non-intrusive. Assessment of rail

track subsurface using DAS does not interfere

with traffic and allows monitoring changes

in real time for more predictive planning of

maintenance operations, especially in areas

with complex geological conditions or high

geotechnical risks.

Chinese JV awarded final section of

$2.2B Tanzania Rail Project

By Shem Oirere

A

Chinese joint venture has won a

second contract in under three years

to construct the sixth phase and final

portion of a 2,561-km standard gauge railway

(SGR) line in East Africa over the next four

years.

China Civil Engineering Construction

Corporation and China Railway Construction

Corporation will build the 506 km line

connecting the towns of Tabora and Kigoma.

The $2.2 billion project is comprised of 411

km of main line, 95 km of branch lines, 10

railway stations and two large freight yards.

Denmark-based engineer COWI A/S was

previously picked as preferred designer of the

Tabora-Kigoma phase of the SGR line project.

As in the previous five phases, the Tabora-

Kigoma phase is being constructed alongside

Tanzania’s existing 2,725.5-km meter-gauge

railway track, reducing the need to establish

right-of-way.

Contracts for five earlier phases of the SGR

line have been awarded to Turkish and

Portuguese contractors. The Tanzanian SGR

line will link landlocked countries of Rwanda,

Burundi and Democratic Republic of Congo

(DRC) to the Indian Ocean port city of Dar es

Salaam. The SGR line, once fully operational,

would reduce cargo transportation costs

between Dar es Salaam and the landlocked

countries from $6,000 per metric ton to

$4,000 per metric ton. Transportation time is

also expected to drop drastically from 30 days

to 30 hours by 2027.

Construction Corporation and China Railway

Construction Corporation signed another

contract for the construction of the fifth phase

of the SGR line, approximately 249-km long,

connecting the town of Isaka to Mwanza, the

second-largest city in Tanzania. The contract

award coincided with Tanzania’s securing a

$1.32 billion loan to finance this phase of the

SGR line.

The SGR line is designed with a lifespan of

100 years, and can handle axle loads of 35

metric tons and a design speed of 160 KPH

(99 MPH) for passenger trains and 120 KPH

(74 MPH) for freight trains. Initially, 24 trains,

with maximum length of 2 km, will travel the

2,561-km electrified SGR line.

The SGR will use UIC 60-type rail on prestressed,

mono-block concrete. According to

the Tanzania Railway Corporation, the SGR

line’s “horizontal curves will be designed to

account for the relatively higher speed of the

new train.”

The SGR line is being laid with 2.6-m-long

sleepers that are spaced 600-mm apart.

The is also utilizing 2.5 cu meters of ballast

for every meter laid. The ballast’s thickness

and shoulder width has been designed

at maximum of 300 mm and 400 mm

respectively.

The rails will be fastened using the elastic rail

fastening-anti vandal system while the track

will have continuously welded joined using

the flush-butt method.

“This Tabora-Kigoma railway will open up

Tanzania and connect it with Democratic

Republic of Congo where there is a lot of

cargo that needs to be transported through

our [Dar es Salaam] port,” said Tanzania’s

President Samia Suluhu Hassan during the

signing of the contract in December 2022.

Tanzania is expected to finance the project

through equity and commercial loans. With

the contract award for the Tabora-Kigoma

section, the total investment in the entire

SGR line project in Tanzania has now risen to

$10.4 billion.

“I know our critics blame us for taking up

these loans, but they must understand that

a better infrastructure is key to driving

growth in our country and making Tanzania

competitive at the regional level,” said

President Samia Suluhu Hassan in December

2022.

Nigeria and Senegal sign

MoU on local content in

Senegal's oil and gas

industry

By Chinedu Okafor

The Nigerian Content Development Monitoring Board, a federal

government body, has signed a Memorandum of Understanding

(MoU) with Senegal's National Local Content Monitoring Agency

to strengthen local content in Senegal's oil and gas industry.

The signing, which took place on Tuesday at the 7th Sub-Saharan

Africa International Petroleum Exhibition and Conference in Lagos,

followed Senegal's preparations for its first oil and gas production

before the end of the year.

This report is courtesy of the Punch NG, a Nigerian news agency.

Senegal's envoy, Deputy Permanent Secretary, COS Petrogaz,

Republic of Senegal, Mamadou Fall Kane, said that Senegal had

much to learn from Nigeria, which had achieved 54% local content

of a 70% target by 2027.

“I conceived this partnership framework with the NCDMB for the

past year, and it is very fulfilling that this event is holding today.

With the signing of this collaboration, Senegal has a lot to learn

from Nigeria on how to deepen its local content target. This would

go a long way to benefit all Senegalese as the country moves

towards developing our natural resources”, he stated.

Simbi Wabote, Executive Secretary of the NCDMB, emphasized

that the cooperation was not just to enhance local content

in Senegal, but also a business-to-business partnership and

capacity building in Senegal.

Mele Kyari, Group Chief Executive Officer of Nigerian National

Petroleum Company Limited, urged collaboration among African

countries to make additional hydrocarbon discoveries on the

continent in his Keynote presentation.

“In the next twenty years, energy demand in Africa is expected

to increase in the order of 30-35% to support the projected

increase in population and industrialization. This presents an

enormous opportunity for us to form partnerships across the

continent and build a sustainable future,” Mele Kyari said.

“The need for partnership is reinforced as more African

countries continue to make hydrocarbon discoveries. We

should collaborate and share knowledge and help each

other in critical areas including technology, exploration and

production, research and development, technical expertise, and

human capacity development to spread the wealth within the

continent,” he added.

African Development Bank’s SEFA

approves $5 million in grants

to set up super energy service

companies in three countries

The Sustainable Energy Fund for Africa (SEFA) of the

African Development Bank has approved a technical

assistance grant of $5.03 million to implement the Africa

Super Energy Service Companies (ESCO) acceleration program

in Rwanda, Senegal and South Africa.

SEFA is a bank-managed multi-donor special fund that works

to unlock private sector investments in renewable energy and

energy efficiency.

Super ESCOs are vehicles that channel funds into public sector

energy efficiency investments such as hospitals, schools, and

street lighting, paving the way for private investment. The

acceleration program catalyzes private sector investments

in energy efficiency by operationalizing Super ESCOs, thus

stimulating the transition toward more sustainable and greener

economies.

The grant will support the training of a team to operate

Super ESCOs and support private ESCOs in the three countries

to develop their Energy Performance Contract services.

Private ESCOs provide services to energy users to design

and implement energy efficiency options. The funding will

also underwrite the development of harmonized regional certification

schemes for ESCOs and energy service professionals, including energy

auditors, managers, and energy savings measurement and verification

professionals.

“This innovative program will enable Senegal to establish its Super

ESCO and boost the energy efficiency market for increased energy

performance in the public and private sectors,” said Mr. Saer Diop,

Director-General of Senegal’s Agence pour l’Economie et la Maîtrise de

Mohamed Chérif, African Development Bank Senegal Country Manager,

said: “Super ESCOs are an efficient tool that governments can draw on

to leverage private sector resources to improve the energy efficiency of

public facilities and other key energy-consuming sectors. I am pleased

that Senegal will be one of the first countries to benefit from the Africa

Super Energy Service Companies Acceleration Program.”

The acceleration program is paving the way for a successful

implementation of downstream energy efficiency investment programs

in which the African Development Bank, the Sustainable Energy Fund for

Africa, and other stakeholders will invest.

ARCHEOLOGY

Surveying in Africa is critical, but unless you have the

correct equipment and trained archaeologists, the field

will be a difficult and time-consuming process.

Archaeology surveying is the process

of gathering information about

the past through excavation and

surveying. It can take a variety of forms and

can be either intensive or non-intrusive.

Archaeology surveying can provide important

information about human activities during

the past. It can be an important step before

archaeological excavations take place.

During archaeological field work in Africa,

geophysical methods are increasingly used.

Until recently, magnetic surveying was not

widely used in sub-Saharan regions. This new

technique is now widely used in sub-Saharan

archaeology. In the Chad Basin, the Zilum site

is part of the Gajiganna Culture and dates

back to 600-400 BC.

Archaeology surveying is an important part

of conservation efforts and can help preserve

and protect African cultural heritage. Through

this project, researchers will document

previously unknown archaeological and

cultural heritage sites. They will focus on

sites that are under threat from urban growth,

conflicts, and infrastructural development.

Researchers will receive in-country training

to identify archaeological sites and maintain

database records.

Surveys are important reconnaissance tools

in African archaeology, but the amount of

surface research is still limited. This article

reviews the state of surface archaeology

in Southern Africa, reviews its role in

landscape archaeology, and considers Bower's

methodological concerns. It also presents a

case study from the Tankwa Karoo region of

South Africa.

Surveying in Africa is critical, but unless you

have the correct equipment and trained

archaeologists, the field will be a difficult

and time-consuming process. But if you have

the proper training and a keen eye, it will

yield rewards. The benefits of conducting

archaeological surveys are significant and

well worth the effort. If you are interested in

learning more about archaeological surveys

in Africa, here are some tips:

The 2004 survey season established an

extensive and diverse archaeological record.

It identified previously undocumented

tell sites on floodplains. The data indicate

three distinct stages in the history of the

region's human settlement: the foraging

phase, a lengthy period of cultivator-forager

economies, and the second phase of smallscale

farming.

An important consideration in archaeological

surveying is visibility. If visibility is good,

researchers will use fieldwalking to

systematically walk through an area looking

for artifacts and archaeological indicators.

They will also take notes about the

surrounding environment at the time. This

method is most effective when the area is flat

and has little vegetation. Because artifacts

tend to move to the surface of the soil,

fieldwalking does not always detect them.

Archaeology surveying methods vary

considerably, but the basic principles of

all methods are the same. The method

of surveying must be appropriate for the

archaeological site and the site's location.

Before deciding on the surveying method,

archaeologists must first define the

study area and become familiar with its

natural characteristics. Another method of

archaeological surveying is by using remote

sensing techniques. These techniques allow

archaeologists to conduct subsurface testing

without disturbing the surface. One technique

uses a proton magnetometer to measure

the strength of the earth's magnetic field.

Unscathed dirt registers a smooth plane when

the device is placed on it. Disturbed dirt, such

as ditches, will alter the magnetic reading.

The method is effective in detecting middens,

ditches, and burned structures.

The Challenges

of Underwater

Electronics

Water or corrosion-resistance is a

necessary application feature for an

underwater electronic device. These

include marine sensors and acoustic

devices that can be used in deep sea

environments or to monitor structures

or other underwater elements.

By Dorcas Kang'ereha

Underwater electronics are

electronic devices that can operate

in the ocean and resist water

penetration or tampering. These devices

are often used in underwater navigation,

positioning and communication systems

for recreational or professional use.

Despite the obvious advantages of this

technology, there are many challenges

to overcome before it is practical to

commercialize such devices. Among

these, a major concern is the resistance

to saltwater and other environmental

conditions.

A common method of achieving waterresistance

is by sealing the device or

circuitry within an outer protective

layer. However, this is not always the

best option since it cannot guarantee

protection from all external forces.

In fact, in order to make a product

completely waterproof it is often

necessary to use a complex sealing

technology involving multiple layers and

various types of sealants.

Another approach to ensuring waterresistance

is by making the device

waterproof in the sense of allowing it to be

immersed in water without damaging the

electronics inside. This is a more advanced

approach and requires specific sealing

techniques to prevent the device from

being penetrated by water.

An example of this is the new generation

of water meters for residential and

commercial usage which have a waterproof

housing which is sealed to ensure that

water can't get in. The system also has a

sensor that monitors the level of water in

the house or commercial building.

There are also many other applications

where water-resistance is a necessary

feature of an electronic device. These

include marine sensors and acoustic

devices that can be used in deep sea

environments or to monitor structures or

other underwater elements.

The development of a waterproof

packaging system is required in these types

of applications because the environment

and operational load are not only from water

but also influenced by other factors like

temperature changes, pressure differences

and other stresses such as mineral aging

effects or microorganisms that can attack the

device in the long term.

To address these issues, a series of new

packaging technologies and materials have

been developed. These technologies are

based on organic potting compounds and

are designed to withstand permanent media

exposure in seawater at a depth of up to 50

meters.

This research is part of the National Science

Foundation-funded project 'The Internet of

Underwater Things' (IoUT) to develop smart

interconnected devices and networks that can

connect underwater vehicles.

Optical Wireless Communication: A New Way

to Communicate Underwater

Underwater optical wireless communication

is a relatively new technology that enables

high data rates and moderate distances

communication in undersea environments

using laser beams of light. This type of

communication could be ideal for a variety

of application such as real-time video

transmission or control of remotely operated

vehicles.

In contrast to acoustic and RF

communications, optical wireless

communication can be a great advantage

due to its higher bandwidth. Moreover, it can

provide more information to the receiver with

low latency.

As the amount of data increases, more and

more applications will be developed for

underwater optical wireless communication.

Consequently, more and more research is

necessary on UOWC technologies in order to

improve the quality of these systems.



AERIAL SURVEY

Aerial Surveying

One of the major technological breakthroughs that has been made in the field of aerial

surveying is the use of LiDAR (Light Detection And Ranging) sensors. This helps to see

through trees and ground cover, which can make it harder for an aerial vehicle to capture

detailed and accurate imagery


AERIAL SURVEY

Drone is an important tool for the world to have when it

comes to aerial surveys, as it allows us to get more accurate

and detailed data without spending as much money on it.

In Africa, a vast amount of land is still

unmapped. Using drones, this can

be easily achieved at a fraction of

the cost. This allows for fast and accurate

mapping in both 2D and 3D. This technology

can be used by a number of industries,

including construction, land surveying,

mining, inspection, agriculture and forestry,

emergency management and humanitarian

response.

Aerial Surveying in Africa

The use of drones for aerial surveying in

Africa has been increasing significantly. It has

become a more environmentally friendly form

of surveying, which is ideal for remote and

difficult-to-reach areas. UAVs are also more

flexible, allowing them to access areas that

would otherwise be difficult or impossible for

manned aircraft.

One of the major technological breakthroughs

that has been made in the field of aerial

surveying is the use of LiDAR (Light Detection

And Ranging) sensors. This helps to see

through trees and ground cover, which can

make it harder for an aerial vehicle to capture

detailed and accurate imagery.

This type of sensor is essential for highly

accurate surveys like mineral exploration,

geophysical surveying and environment

monitoring. It has also made it possible to

collect high-density point cloud data for use

in Geographic Information Systems.

Aerial Digital Imagery

The use of aerial digital imagery has been

increasing in Africa over the years. This is

mainly because it is faster and easier to

collect than traditional analogue techniques,

as well as providing excellent spatial and

spectral resolutions.

During the past decade, Africa has witnessed

a significant change in the aerial digital

imagery sector. This was primarily because

of the development of a number of different

specialized sensor technologies which allow

for a range of different applications.

Another key change in the aerial digital

imagery sector has been the emergence of

new software and algorithms that allow for

greater accuracy and efficiency. Moreover, this

has enabled users to have more flexibility

when it comes to the way they use this data.

Aerial digital imagery can also be used for

more precise crop surveys, such as when

determining the crop yield in a given area or

analyzing the effects of different soil types.

This can help farmers to better manage their

crops in order to maximize their yield.

It can also be used for assessing the condition

of a site and identifying potential hazards.

This helps to protect the environment and

improve the safety of both people and

animals.

The development of drones with advanced

imaging technologies is changing the way

we do surveys in Africa and globally. This

has created a market that is growing rapidly

and is expected to continue doing so in the

coming decades.

This is an important tool for the world to

have when it comes to aerial surveys, as it

allows us to get more accurate and detailed

data without spending as much money on it.

It has also been proven to be safer and more

efficient than traditional methods.

By Reportlinker

The global autonomous marine

vehicles market is expected to grow

from $1,994.26 million in 2021 to

$2,298.08 million in 2022 at a compound

annual growth rate (CAGR) of 15.2%. The

Russia-Ukraine war disrupted the chances of

global economic recovery from the COVID-19

pandemic, at least in the short term. The

war between these two countries has led to

economic sanctions on multiple countries,

surge in commodity prices, and supply chain

disruptions, causing inflation across goods

and services effecting many markets across

the globe. The autonomous marine vehicles

market is expected to grow to $4,147.97

million in 2026 at a CAGR of 15.9%.

The autonomous marine vehicles market

consists of sales of submarine gliders and

autonomous underwater vehicles.Values in

this market are ‘factory gate’ values, that is

the value of goods sold by the manufacturers

or creators of the goods, whether to

other entities (including downstream

manufacturers, wholesalers, distributors and

retailers) or directly to end customers.

The value of goods in this market includes

related services sold by the creators of the

goods.

Autonomous marine vehicles are robotic

equipment that travels below or on the

surface of the water without requiring input

from a human operator.

North America was the largest region in the

autonomous marine vehicles market in 2022.

Middle East was the second largest region in

the autonomous marine vehicles market.

The regions covered in the autonomous

marine vehicles market report are Asia-

Pacific, Western Europe, Eastern Europe, North

America, South America, the Middle East, and

Africa.

The main types of autonomous marine

vehicles are surface vehicles and underwater

vehicles.A surface vehicle is a car for

transportation on land, as opposed to a

subway car or any other elevated car.

The different applications involved

are military & defence, archaeological,

exploration, oil & gas, environmental

protection and monitoring, search and

salvage operations, and oceanography.

The technologies involved are imaging,

navigation, communication, collision

avoidance, and propulsion.

The autonomous marine vehicle market

is being driven by a rise in hydrographic,

oceanographic, and environmental surveys

conducted globally.A hydrographic survey

measure describes and maps features that

can be found underwater.

The main purpose of conducting these

surveys is to produce navigational charts

essential for the safe transit of vessels.

An oceanographic survey helps with the

accurate understanding of marine and

freshwater environments for port and harbour

development, wastewater and industrial

outfalls, power plant intakes and outfalls, and

offshore disposals.

An autonomous surface vehicle (ASV)

provides an efficient method of undertaking a

hydrographic survey, as it saves both cost and

time.It is also flexible and convenient, which

allows for faster deployment for several

survey requirements, from event surveys to

large coastal surveys.

For instance, according to the world’s first

autonomous hydrographic survey, by 4D

Ocean, after the channel Coastal Observatory

(CCO) commissioned it to carry out a

hydrographic survey of the seabed that is

offshore of Hurst Spit, Western Solent, with

the help of a SeaRobotics ASV 2.5.

The vulnerability of ships to cyber threats

due to automation is a major restraint for the

autonomous marine vehicle market.This is

mainly because cyberspace and its associated

infrastructure are vulnerable to a versatile

range of risks coming from cyber threats and

attacks.

The use of automation, which negates the

need for human intervention on ships and

in ports, increases the chances of security

breaches.A cyber-attack can misguide an

autonomous ship to move in a different

direction or move to a separate port, which


AUTONOMOUS MARINE VEHICLES

can lead to misplacement and delay of goods

and services.

For example, container ship and supply vessel

operator A.P. Moller-Maersk became a victim

of a cyber-attack that resulted in a loss of

around $250–300 million for the company.

According to a survey by law firm Clyde &

Co and the Institute of Marine Engineering,

Science & Technology (IMarEST), over twothirds

of marine industry executives surveyed

from across the world fear that unmanned/

autonomous ships present a greater cybersecurity

risk than traditional ships.

Maritime drone swarming for better

surveillance and investigation capabilities is

an emerging trend in the autonomous marine

vehicle market.Maritime drone swarms are a

large group of underwater vehicles moving

together for a particular purpose.

The drone swarm has a wide range of

capabilities in defence applications since it

is capable of performing surveillance and

investigation tasks followed by defensive

or offensive countermeasures.As the swarm

works collectively to navigate through

the underwater environment, it senses a

wider area in a shorter time by making use

of several sensing techniques to build a

comprehensive map of the environment.

For instance, the European Union (EU)

is currently funding a research project

called Ocean2020, which will facilitate

a combination of drones and unmanned

submarines into swarms or fleet units. In

another example, the US Navy’s Undersea

Warfare Center approved a grant of $78,000

for Aquabotix’s SwarmDiver technology to

support the US Navy and allied vessels.

The International Maritime Organization

(IMO) has regulations related to ballast water

management in marine vehicles.Ballast water

is defined as water that is pumped inside a

marine vehicle to maintain safe operating

conditions and operations.

Regulation D-3 by the IMO requires that

ballast water management systems that use

active substances be approved following

the specifications defined by the IMO.As per

the International Convention for the Control

and Management of Ships’ Ballast Water and

Sediments, active substances are those which

include a virus or a fungus, having a general

or specific action on or against harmful

aquatic organisms or pathogens.

Hence, regulations such as these would

keep a check on manufacturers of ballast

water management systems as well as the

companies in the autonomous marine vehicle

market.

DRONES

Google company unveils drone

delivery-network ambition

By Chris Vallance

A

subsidiary of Alphabet, which owns

Google, hopes to develop drone

delivery-network technology able to

handle millions of orders, within 12 months.

Operating drones as a network, Wing says,

will improve efficiency.

The technology is being tested "at scale" in

Logan, Australia, where Wing delivers up to

1,000 packages a day. The company has also

started trial drone deliveries in the Dublin

suburb of Lusk.

And it says it and other companies are in

talks with the Department for Transport and

the Civil Aviation Authority about agreeing

regulations to allow drone deliveries in the

UK.

'Coffee delivery'

Chief executive Adam Woodworth says

the delivery system will look "more like an

efficient data network than a traditional

transportation system".

In the trial, "we do a lot of grocery delivery, we

do a lot of prepared food delivery, we do a lot

of coffee delivery", he says.

At present, consumers are not charged extra

for drone deliveries. The company is not

disclosing what they may ultimately cost.

But to be financially viable, drone companies

will have to make a large number of

deliveries, experts say.

'Big data'

Dr Steve Wright, of the University of West of

England, said it was unsurprising Wing was

one of the companies trying to do so.

"Everybody is still working on the drones

themselves - these things are going to

operate night and day, far longer than we've

done before - but thoughts are already

turning to the bigger picture," he said.

"The first question that is being grappled

with right now with is regulation. However,

the next question is looming large - how to

manage and direct this vast number of robots.

I don't think that it's any coincidence that

Wing and Amazon share one clear heritage -

big data."

DRONES

A Wing drone flying in Lusk Image: WING

The Wing Delivery Network comprises three

basic hardware elements.

• the delivery drones

• pads where drones take off, land and

recharge their batteries

• autoloaders that allow companies to

leave packages for collection

Using these elements, the company says,

drones can pick up, drop off, travel, and

charge in whatever pattern makes the most

sense for the entire system - rather than just

flying from one base to a customer and back.

"A tangible example of that would be: the

aircraft takes off at one location, it might

fly to another business to go pick up a box,

and then it might fly to the delivery location

and then, rather than returning to the pad

it took off from, fly to another adjacent one,"

Mr Woodworth told the BBC's Tech Tent

An advantage of the system working as a

network is it is able to quickly adapt to peaks

in demand in particular areas. Charging-pad

locations can also be added rapidly.

The system also involves a high level of

automation - when an aircraft is turned on,

the company says, it checks it:

• is in the right place

• has the right software

• is approved to fly

And ground-based pilots can supervise

fleets of delivery drones to ensure they are

operating safely and efficiently - rather than

just monitoring a single aircraft.

Mr Woodworth said more civil-aviation

regulators around the globe were adopting

rules that would allow these sorts of

operations.

But there are challenges to be overcome.

Wing has faced complaints about noise from

some Logan residents.

The company has invested "a lot of work into

making the aircraft as quiet as they can be",

Mr Woodworth says. And planning software

has been designed to avoid creating "drone

highways", where every flight passes over the

same houses.

GROUND PENETRATING RADAR

Ground

Penetrating

Radar

Ground Penetrating Radar (GPR) is an electromagnetic

technique that can detect changes in the subsurface

without disturbing the surface. It works at a low

frequency and can reach depths of 30 to 40 meters. The process

is non-destructive, safe, and accurate. It can identify metallic and

non-metallic objects, voids, and other structures. It can also be

used to detect excavations, back-filled areas, and other ground

disturbances.

GPR is most effective in favorable conditions, such as sandy soils,

which allow the transmission of the radar pulse. It is unique in

its ability to detect small objects and determine their depths.

However, it has limitations when used in less-than-ideal conditions.

In particular, fine-grained sediments can scatter the radar signal,

which limits its depth penetration.

The total round-trip time between the antenna and the subsurface

feature is important for determining how far the radar can

penetrate. This time is dependent on the amount of scattering

and EM energy that is released from the target. The amount of

scattering depends on the water content of the subsurface and the

concentration of free ions in the soil. Additionally, heavy vegetation,

water on the surface of the ground, and other factors can affect the

EM wave.

GPR works by sending high-frequency electromagnetic waves through

the subsurface. These waves then reflect back to the receiving antenna.

This process allows GPR to detect changes in the EM properties of

the materials. EM properties vary according to the type of soil or rock

material, bulk density, and water content. An antenna is placed on the

ground surface, and the signals are reflected off the boundary where

there is a difference in EM property.

GPR can penetrate up to 100 feet in some cases. However, its depth is

limited by the conductivity of the material. High-conductivity materials

such as granite and limestone will not absorb the waves as quickly as

lower-conductivity materials do. However, the depth of GPR penetration

can be determined using the information gathered by GPR.

GPR is an effective tool for mapping underground utilities and locating

materials inside concrete. The technology has many applications

in engineering and construction. It can also be used for structural

assessment. For example, it can determine the level of degradation of

concrete in a structure, enabling remediation efforts.

GPR equipment consists of a transmitter and receiver antenna

and a radar control unit. The control unit synchronizes the signals,

controls the transmitter and samples the receiver, and transmits

the signals to a recording or display device. The resulting images

are then processed and interpreted.

Ground Penetrating Radar is an effective and versatile tool for

detecting metallic objects. It works best when targets are made

of high contrast, such as metallic materials. The versatility of

this technique makes it an invaluable tool for a wide variety of

practices. In addition to its effectiveness for detecting underground

structures, it can also be used for archeological research.

the US, Plans to Expand Operations

Nuclear-Power plant |image: MDPI

By Jamie Redman

Terawulf, a bitcoin mining operation, has

announced that it has energized the

first nuclear-powered bitcoin mining

facility in the United States at the company’s

Nautilus Facility in Pennsylvania. According

to the company, approximately 1 exahash per

second (EH/s) or close to 8,000 applicationspecific

integrated circuit (ASIC) bitcoin

miners are now online, and another 8,000

mining rigs will be delivered shortly.

Nuclear-Powered Bitcoin Mining — A

Milestone for Carbon-Free Bitcoin Mining

Terawulf announced that the first behindthe-meter

bitcoin mining facility powered

by nuclear energy has been energized,

with nearly 8,000 ASIC mining rigs now

operational. The current 8,000 account for

1 EH/s of SHA256 hashpower, but Terawulf

expects to deploy another 8,000 miners in

the coming weeks to reach 1.9 EH/s by May.

According to the company’s press release

about the Nautilus energization, Terawulf

will receive a fixed electricity rate of around

$0.02 per kilowatt-hour (kWh) for the next

five years.

The Nautilus facility is considered a milestone

as it is the first bitcoin mining facility of its

kind to receive carbon-free energy 24/7 from

the 2.5 GW Susquehanna nuclear plant in

Pennsylvania. “With the recent energization

of the Nautilus facility earlier this month,

approximately 16,000 of Terawulf’s owned

miners, representing 1.9 EH/s of self-mining

capacity, are on-site and being brought online

daily,” said Paul Prager, the chairman and CEO

of Terawulf, in a statement. “The Nautilus

nuclear-powered mining facility benefits from

what is arguably the lowest cost power in the

sector, just $0.02/kWh for a term of five years.”

While 2022 was rough on bitcoin mining

operations, 2023 has been easier on bitcoin

miners due to a significant rise in the price

of bitcoin (BTC) since the end of last year.

Additionally, several firms are expanding

mining operations, with some locating to

Pennsylvania. Seven days ago, Mawson

Infrastructure Group launched a mining

operation based in Pennsylvania after

exiting Australia. In addition to the 50-MW

Nautilus facility, Terawulf announced that it

is expanding operations at its Lake Mariner

facility in New York. This move will increase

the Lake Mariner operation from 60 MW to

110 MW.


MINING

Reviving Nigeria’s neglected

$700bn mining sector

By Natasha Teja

Amid the global push for green

energy solutions, Nigeria’s reserves

of critical minerals such as lithium,

manganese and nickel are in high demand,

prompting the government to release a series

of initiatives that will fast-track foreign direct

investment into the sector.

On February 8, the Africa Finance Corporation

(AFC), a pan-African multilateral development

financial institution, established a partnership

with the Nigerian mining sovereign wealth

fund, Solid Minerals Development Fund

(SMDF). The partnership aims to accelerate

commercial scale, private sector-led mining

projects by providing much-needed funding

and technical advisory.

Nigeria’s mining sector boasts 44 different

types of commercially viable minerals

worth an estimated $700bn, according

to SMDF estimates; but limited capital

injections, inadequate geo-mapping tools and

widespread illegal mining have left the west

African nation struggling to capitalise on its

reserves.

Hajiya Shinkafi, CEO of SMDF tells fDi: “We

will target all these minerals and more.

Ongoing exploration efforts in Nigeria have

identified excellent lithium prospects that we

will look to support.”

Ongoing exploration efforts in Nigeria have

identified excellent lithium prospects that we

Hajiya Shinkafi, CEO at SMDF: "One of the key

issues stalling the sector’s growth is the lack

of sophisticated geo-scientific data gathering

tools. For decades, corporations have largely

relied on illegal mining activities to gather

information on the types, quantities and

locations of minerals available."

“Historically, it’s actually been one of the

main pathfinders for a lot of junior mining

companies to make these discoveries,” says

Hard work:

Segun Lawson, CEO at Thor Explorations — a

Canada-listed mining firm that heads AFC’s

flagship gold mine project in Nigeria.

“These illegal miners are mining at a much

smaller scale with rudimentary methods,

and then larger corporations are following

off the backs of these small discoveries,” he

adds. Illegal mining caused an outbreak of

lead poisoning in 2010 that affected 18,000

people and killed at least 200 children,

according to a report by the UN. Unfazed

by its risks, artisanal miners continue to

dominate mining activities in Nigeria’s northwestern

regions. “However, if you look across

west Africa there are a lot of artisanal and

illegal mining, it’s not just unique to Nigeria,”

Mr Lawson says.

Reports of banditry and insurgencies across

several mining areas, including Nigeria’s

states of Zamfara and Kaduna, have also

discouraged foreign investors. In November

2022, a local terror group threatened to

attack a gold mine in the Bukuyum local

government area of Zamfara after miners

refused to pay a 10% levy.

During a local interview conducted last

month, Nigeria’s minister of mines and steel

development admitted that “we do not have

the resources to pre-empt all these illegal

activities because Nigeria is vast”.

Instead, the government has turned its focus

on data gathering projects to add legitimacy

to the sector. Osam Iyahen, senior director and

head of natural resources at AFC, tells fDi that

“the Nigerian government has taken steps

to enable a more accurate delineation of the

types and quantities of minerals available by

tapping into a funding programme with the

World Bank to advance airborne geo-mapping

exercises”.

The Nigerian government is also supporting

a large number of infrastructure initiatives to

build transportation links for the movement

of equipment to mining sites and the

evacuation of minerals for sale and export.

Prior to AFC’s partnership with SMDF, the

development institution collaborated with

Thor Explorations to finance the Segilola

Gold Mine. The mine is currently Nigeria’s

most advanced gold project after achieving

commercial production in 2021.

The company’s CEO hopes that its success will

catalyse foreign investments into the country,

but acknowledges the challenges that mining

projects face.

“Statistically speaking, the number of

conversions from an exploration license

to a discovery is very low. Then from an

exploration to an operation license, that

number is even lower,” says Mr Lawson.

However, he adds: “Consistent exploration and

more success stories will only lead to further

growth in the sector.”

By Jason Mitchell

African countries must allow the

mining of minerals to happen if

they are to experience significant

economic growth, but they have to find a

way of minimising the damage to the natural

environment and to ensure that profits help

local communities.

Africa is a massive region, covering three

times as much ground as Europe, across 54

countries, and with a total population of 1.4

billion, which is expected to reach 2.5 billion

by the end of 2050. However, it is also the

world’s poorest region; in 2021, sub-Saharan

Africa had an annual income of $1,600 per

head compared with $8,300 in Latin America

and the Caribbean and $13,000 in East Asia

and the Pacific. In 2022, the UK had a bigger

economy than the whole of Africa combined;

$3.48tn versus $2.96tn.

In 2021, it is estimated that 490 million

Africans lived under the poverty line of $1.90

purchasing power parity equivalent per

day, 37 million people more than what was

projected without the Covid-19 pandemic.

Africa requires economic growth and lots

of it if its to lift its people out of poverty.

Economists estimate that a low-income

country must grow at more than 6% a year

over many years to start to see significant

poverty reduction. The International Monetary

Fund estimates that the sub-Saharan

economy expanded by only 3.6% in 2022 and

forecasts that it will grow by only 3.7% in

2023. That is just not good enough.

Following China’s example

The mining industry provides an obvious

source of wealth for Africa, and recent

developments in China could prove to be

something of a blueprint for African countries.

Since China began to open up and reform its

economy in 1978, GDP growth has averaged

over 9% a year and more than 800 million

people been lifted out of poverty, exactly the

kind of change that Africa needs.

Africa has some of the world’s biggest

deposits of minerals, which are not only

valuable in their own right, but could prove

essential to the energy transition. Nickel,

cobalt, graphite, lithium, and rare earth

elements are all in high supply; for instance,

Africa accounts for around 80% of the world’s

total supply of platinum, 50% of manganese

and two-thirds of cobalt. The continent also

holds 40% of the world’s gold reserves and up

to 90% of its chromium.

Countries like South Africa, Madagascar,

Malawi, Kenya, Namibia, Mozambique,

Tanzania, Zambia and Burundi enjoy

significant quantities of important rare earths,

including neodymium, praseodymium and

dysprosium. Ghana is the continent’s largest

producer of gold, followed by South Africa and

Mali. The Democratic Republic of the Congo

(DRC) is Africa’s largest industrial diamond

producer, followed by Botswana and South

Africa.

Yet there is a disparity in the continent’s

mining industries. Africa is endowed with

about 30% of the planet’s mineral reserves,

but in 2019, it only produced around 5.5% of

the world’s minerals and its global share was

valued at $406bn that year, according to the

World Mining Congress.

African countries must exploit their mineral

wealth. The DRC, for example, has a total

mineral wealth estimated in the tens of

trillions of dollars but the average Congolese

person only earns $700 a year. Guinea — a

small West African country with only 13.5

million inhabitants — enjoys massive and

high-quality bauxite reserves: some 7.4bn

metric tons, 23% of the world’s total. Its

supply is vital to global aluminium production

and for the energy transition to go ahead

but the average Guinean only earns $1,440

a year.

By 2040, at least 30 times as much lithium,

nickel and other key minerals may be

required by the electric car and battery

storage industries to meet global climate

targets, according to the International Energy

Agency (IEA). Similarly, the rise of low-carbon

power generation to meet climate goals

means a tripling of mineral demand from this

sector by 2040. In May 2021, the IEA declared

that the world is undergoing a massive

industrial conversion that marks a “shift

from a fuel-intensive to a material-intensive

energy system”.

Minimising environmental impacts

The potential for mineral transformation

creates an enormous economic opportunity

for Africa. However, increased mining in the

region throws up two major issues that do

need addressing — natural habitat loss and

inequality. In the end, both these problems

are a question of governance.

Further mining will inevitably result in

greater deforestation. It is not only the new

mining sites that will destroy forests but also

all the associated roads and new settlements.

The region is already seeing massive

destruction of its natural habitat. In 2020, the

continent had 636.64m hectares of forest,

16% of the world’s total. But it witnessed the

greatest annual rate of net forest loss of any

region in the world — at 3.94m ha — between

2010 and 2020.

There is also a big question mark around

whether the local communities really gain

much economically from all the new mining

activity. This is not a challenge unique to

Africa; in many cases, it is the elites in

wealthy capital cities that enjoy most of the

financial rewards from mining.

In Africa specifically, foreign miners

headquartered in Europe, North America and

China eager to expand their portfolios adds

another dimension to this issue, and another

type of actor who could take revenue away

from local workers.

The need for better governance in Africa

If African countries had better governance,

increased mining would not be such a

controversial issue. Africa requires ‘responsible

mining’, defined as mining that involves and

respects all stakeholders, minimises and

takes account of its environmental impact

and prioritises a fair division of economic and

financial benefits. But the crux of the problem

is that for responsible mining to really work,

a country needs good governance in the first

place and most African countries just do not

have it.

Transparency International’s Corruption

Perceptions Index ranks 180 countries

by their perceived levels of public sector

corruption on a scale of zero (highly corrupt)

to 100 (very clean). In 2021, the sub-Saharan

Africa average was 33 — the lowest in the

world — and 44 African countries ranked

below 50.

Improving governance in Africa is not an easy

thing to do. Many African countries are fragile

democracies at best, and in a number of cases

they are outright dictatorships. Whenever

possible Western governments need to bear

pressure on African governments to take

steps to become better, more sophisticated

democracies, or at least implement aspects

of governance such as labour rights and

environmental protection.

That in itself is not a straightforward task for

many Western governments to do without

being accused of colonial-style interference,

and reflects a paradox at the heart of much of

African mining: more effective mining could

deliver great economic benefits and a sense

of autonomy for local groups, but should this

mining come from foreign companies and

over-reaching Western powers, there is a risk

of it all being for nought.

Africa stands at an economic threshold.

The energy transition – through increased

mining – could improve the region’s wealth

immeasurably. It is an economic opportunity

that must be seized. However, it falls on the

continent’s next generation to ensure that

their governments are more accountable and

that a lot more mining can be balanced at

least to some extent with conservation of the

natural environment. They must also ensure

that the economic benefits of more mining

are more evenly spread.
