NEWS BRIEFS 

Exciting Discoveries in Tanzania’s Ruvuma PSA 

A 

recent data interpretation operation 

by ARA Petroleum Tanzania has 

revealed some exciting news about 

the Ruvuma PSA. A 3D survey conducted by 

Aminex has shown a significant increase in 

resource potential in the wider license area. 

This survey has uncovered 338 sq km of new 

data, leading to some promising results. 

Through seismic inversion geomodeling with 

Ikon Geoscience, there has been a notable 

improvement in the in-place volumetrics for 

the Ntorya gas discovery. It is estimated that 

around 3.45 trillion cu/ft of gas initially in 

place (GIIP) could be found in the reservoir 

sandstones of the Ntorya-1 (NT1) and 

Ntorya-2 (NT-2) discovery wells. 

Potential Future Discoveries 

The new 3D seismic images suggest the 

presence of even more gas-charged reservoir 

sandstones, potentially leading to additional 

gas volumes. There is also hope for the 

discovery of an as yet undrilled shallower 

sand unit (Unit 3) to be tested by the 

upcoming Chikumbi-1 (CH-1) appraisal well.

throughout the three days of the event – on the growing synergy 

between geodesy and the digital building industry, including aspects 

such as integration in BIM processes and sustainable carbon-neutral 

construction, renovation and maintenance. 

A FOCUS ON EARTH OBSERVATION 

One of the aims of INTERGEO 2024 is to establish itself as the 

leading international event relating to Earth observation. Earth 

observation is hugely important for a whole variety of applications, 

from climate research and urbanisation processes to agriculture. One 

key focus is the use of Earth observation data to support sustainable 

developments and deal with global challenges such as climate change. 

In view of extreme weather events, loss of biodiversity and pressure 

to urbanise, Earth observation data provides essential information for 

efficient adaptation and mitigation strategies. 

The innovative Earth observation technologies being showcased at 

INTERGEO 2024 are crucial for understanding and monitoring climaterelated 

phenomena. High-resolution satellite images and advanced 

analytical methods make it possible to precisely document and 

analyse changes in ecosystems, sea levels and glacial melting. This 

information is vital for developing climate adaptation strategies and 

reducing CO2 emissions. The INTERGEO 

Conference will include sessions on topics such as “Earth Observation 

for Managing the Green Transition” and “From Climate Change to 

Climate Adaptation – Consequences and Measures” (“Von Klimawandel 

zu Klimaanpassung – Konsequenzen und Massnahmen”) that will 

highlight the essential role played by Earth observation in society 

today. A keynote speech entitled “Earth Observation for our World in 

Change” will address the current challenges and solutions in relation 

to Earth observation. 

As technologies become increasingly advanced and as more and more 

Earth observation data becomes available, these technologies and 

data will become even more relevant in the commercial landscape, 

opening up new business opportunities and helping to solve global 

challenges. According to recent data from market research company 

Euroconsult, for example, many new countries are joining the satellite 

manufacturing industry. Over the next decade, more than 3,500 

EO satellites will be launched and close to 98 billion US dollars 

of revenues will be generated. This is almost triple the number of 

satellites launched between 2012 and 2021, and a 23 percent growth 

in market value. (Source: https://www.euroconsult-ec.com/pressrelease/global-market-for-commercial-earthobservation-data-andservices-to-reach-7-9-billion-by-2031/). 

PARTNERSHIPS FOR A SUSTAINABLE FUTURE 

In September 2024, the halls of Messe Stuttgart will turn into a living 

mosaic – the approximately 17,000 participants who are expected to 

attend the event from all over the world will transform INTERGEO into 

a global centre for geoinnovation, where the international community 

of geospatial experts will gather together to shape the world of 

tomorrow. 

Besides bringing the international community together, however, 

INTERGEO 2024 will also demonstrate how global dialogue can lead 

to changes at local level. From urban planning that is inspired by 

international best practices to climate protection projects that are 

based on worldwide data – the event clearly demonstrates that the 

answers to local issues are often to be found in global dialogue. 

The event offers a unique opportunity to gain insights into the future 

of geoinformation and Earth observation and to set the right course 

for the years to come. It invites the global community to become 

part of a movement that is shaping a sustainable future through 

innovation, technology and the sharing of knowledge. 



COVER STORY 

The Impact of Climate 

Change on Marine Surveying 

Adapting to the Rising Sea Levels 

By Dorcas Kang’ereha 

Climate change poses a significant 

threat to our planet, with the rising 

sea levels being one of its most visible 

and impactful consequences. As the world’s 

oceans continue to swell, the role of marine 

surveying in understanding and adapting to 

these changes has never been more essential. 

Climate change and global warming are real, 

and they are causing water levels to rise. This 

rise in water levels poses a serious threat to 

river, dam and coastal areas in Africa. 

Climate change refers to long-term changes 

in temperature, precipitation, and other 

atmospheric conditions on Earth. Global 

Climate change knows no borders, international cooperation 

is essential in mitigating its effects on marine environments. 

Countries can work together to address the challenges 

posed by climate change in marine surveying, navigating 

uncharted waters with confidence and contribute to a 

brighter future for our water resources and planet. 

warming, a major driver of climate change, is 

primarily caused by human activities such as 

burning fossil fuels and deforestation. These 

activities release greenhouse gases like 

carbon dioxide into the atmosphere, trapping 

heat and causing the planet to warm up. 

Impact of Climate Change on 

Rising Sea Levels 

The impact of climate change on rising 

sea levels is profound. Coastal erosion, 

increased flooding, and saltwater intrusion 

into freshwater sources are just a few of 

the consequences. The need to adapt and 

mitigate these effects is crucial for the 

survival of water area communities and 

ecosystems.

LIDAR TECHNOLOGY 

The Transformative Impact of 

LiDAR Technology on Hydrographic 

Surveying Practices 



By using laser beams to measure distances and create detailed three-dimensional models, 

LiDAR enables hydrographic surveyors to capture accurate and precise data like never before. 

In the depths of the ocean lies a world 

waiting to be explored and understood. 

Hydrographic surveying, a vital practice for 

mapping the underwater terrain, has been 

revolutionized by the incredible capabilities 

of LiDAR technology. Imagine a tool that can 

accurately measure water depths, map the 

seafloor with precision, and detect submerged 

objects with ease. LiDAR technology does all 

this and more, offering a gateway to a realm 

of possibilities in hydrographic surveying. 

LiDAR (Light Detection and Ranging) has 

emerged as a powerful tool that uses laser 

beams to measure distances and create 

highly detailed and accurate representations 

of underwater landscapes. By capturing 

millions of data points per second, LiDAR 

enables hydrographic surveyors to quickly and 

comprehensively map underwater features 

with unparalleled precision. 

The impact of LiDAR technology has greatly 

improved the efficiency and accuracy of 

hydrographic surveying, saving both time and 

resources. With LiDAR’s ability to penetrate 

water, Hydrographic surveyors can now 

easily visualize underwater topography, 

detect submerged hazards, and accurately 

measure depths. As a result, this breakthrough 

technology has allowed for safer navigation, 

enhanced planning, and improved 

understanding of the marine environment by 

provides highly detailed and comprehensive 

data that is crucial for various industries, such 

as coastal engineering, offshore exploration, 

and environmental monitoring. 

“It could sound obvious that the development 

of surveying technologies has made 

coastal management impossible without 

hydrographic data analysis. Additionally, 

the rise of airborne surveying solutions 

has allowed to increase the scale, speed 

and accuracy of data collection and 

fasten decision making on coastal flood 

risk assessments, seabed predictions 

and environmental monitoring,” asserts 

Alexander Lopukhov, BDM and Co-founder at 

TOPODRONE. 

This cutting-edge innovation has quickly 

become a game-changer in the field, 

particularly in the realm of 3D mapping and 

underwater terrain visualization. By using 

Alexander Lopukhov, BDM and co-founder at 

TOPODRONE 

laser beams to measure distances and create 

detailed three-dimensional models, LiDAR 

enables hydrographic surveyors to capture 

accurate and precise data like never before. 

Limitations of Traditional 

Surveying Techniques 

One of the main limitations of traditional 

surveying techniques was the inability to 

accurately capture the complex topography 

of underwater terrain. Echo sounding, for 

example, could provide depth measurements 

but failed to provide a complete picture of 

the underwater environment. This made it 

difficult to identify submerged structures, 

underwater vegetation, or any other features 

that could impact navigation or resource 

exploration. 

The Emergence of LiDAR 

Technology in Hydrographic 

Surveying 

Unlike traditional methods, LiDAR uses laser 

beams to measure distances and create 

detailed 3D representations of underwater 

landscapes. By emitting laser pulses and 

measuring the time it takes for the pulses 

to return, LiDAR can capture millions of data 

points per second, resulting in highly accurate 

and comprehensive maps. 

One of the key advantages of LiDAR 

technology is its ability to penetrate water. 

Laser beams can travel through water without 

significant loss of signal strength. This allows 

LiDAR to capture detailed data even in turbid 

or murky waters, which is particularly useful 

in coastal areas and estuaries where water 

conditions can vary. 

LiDAR technology also offers a faster data 

collection process compared to traditional 

methods. With the ability to capture a large 

number of data points in a short amount 

of time, hydrographic surveyors can cover 

larger areas in a fraction of the time it would 

take using traditional surveying methods. 

This not only saves time but also reduces 

costs associated with data collection and 

processing. 

Advantages of LiDAR 

Technology in Underwater 

Terrain Visualization 

LiDAR technology offers several advantages 

in underwater terrain visualization, making it 

an invaluable tool for hydrographic surveyors. 

One of the key advantages is the ability 

to accurately measure depths. Traditional 

methods such as multibeam echo sounders 

can struggle with accuracy, especially in 

complex underwater terrains. LiDAR, on the 

other hand, provides highly accurate depth 

measurements, allowing for safer navigation 

and more precise planning. 

“Such technologies as UAV LiDAR bathymetry 

accompanied with airborne photogrammetry 

or echo-sounding bathymetry help to provide 

an advanced outlook on the areas dangerous 

and/or difficult to map with survey vessels,” 

adds Lopukhov. 

Another advantage of LiDAR technology is 

the ability to detect submerged hazards. 

Shipwrecks, underwater cables, and other 

submerged objects can pose a significant 

risk to navigation and offshore operations. 

LiDAR can quickly and accurately detect these 

hazards, allowing for effective mitigation 

measures to be put in place. This not only 

improves safety but also reduces the risk of 

damage to underwater infrastructure. 

Market Trends in LiDAR 

Technology for Hydrographic 

Surveying 

The market trends surrounding the use 

of LiDAR in hydrographic surveying are 

impressive. The demand for this technology 

is fueled by the need for more efficient 

and accurate data collection, as well as the 

growing recognition of LiDAR’s potential in 




improving mapping and navigation systems. 

One key trend in the market is the increasing 

adoption of mobile LiDAR systems. Mobile 

LiDAR systems are mounted on vehicles or 

boats, allowing surveyors to collect data 

while in motion. This eliminates the need 

for manual measurements and significantly 

speeds up the surveying process. Mobile 

LiDAR systems also offer improved safety 

for surveyors, as they can collect data from 

a safe distance, especially in challenging or 

hazardous environments. 

Alexander Lopukhov talks about 2 key 

market trends on the transformative impact 

of LiDAR technology on hydrographic 

surveying practices. The first one is the rapid 

development of a very competitive market 

for airborne bathymetric LiDAR systems. 

Such systems are typically heavy and 

require heavy-lift multirotor drones to carry 

them. The other trend is the combination 

of multiple airborne surveying methods: 

with a photogrammetry camera, LiDAR and 

echo sounding device. A UAV equipped with 

topobathymetry tools usually flies higher. 

“Even though mapping LiDAR might have 

limitations in depth measurements towards 

hydrographic LiDAR, it might be rational for 

a surveyor to opt for a combo solution for 

coastal monitoring tasks and benefit both 

from surface and water area data collection 

with the same UAV. Moreover, depending on 

a hardware producer the same LiDAR can be 

used for mobile mapping, mounted on a car or 

a backpack,” concludes Lopukhov. 

Another trend is the integration of LiDAR 

technology with other sensors and systems. 

LiDAR data can be combined with data 

from other sensors such as GPS, sonar, and 

cameras to create comprehensive and multidimensional 

datasets. This integration allows 

for more accurate and detailed analysis, 

enabling surveyors to make well-informed 

decisions based on a holistic understanding 

of the surveyed area. 

The market trends also indicate a growing 

demand for LiDAR technology in emerging 

markets. As hydrographic surveying practices 

become more prevalent worldwide, the need 

for advanced surveying tools like LiDAR is 

increasing. Companies that specialize in 

LiDAR technology are witnessing a surge 

in their market share, as they continue to 

innovate and develop solutions tailored to 

the needs of hydrographic surveyors. 

Conclusion: The Future 

of LiDAR Technology in 

Hydrographic Surveying 

LiDAR technology has transformed 

hydrographic surveying practices, bringing 

about a new era of 3D mapping and 

underwater terrain visualization. Its accuracy, 

speed, and detailed data capture capabilities 

have revolutionized the way we study and 

understand underwater landscapes. The 

benefits of LiDAR technology, including 

improved efficiency, safer navigation, and 

enhanced planning, are evident in various 

industries. 

As LiDAR technology continues to evolve 

and become more accessible, its impact on 

hydrographic surveying practices will only 

continue to grow. Advancements in hardware 

and software are expected to further enhance 

the capabilities of LiDAR systems, allowing for 

even greater accuracy and efficiency. Ongoing 

research and development, collaboration 

among stakeholders, and continuous 

professional development are crucial 

in unlocking the full potential of LiDAR 

technology in hydrographic surveying. 

The future of LiDAR technology in 

hydrographic surveying holds great promise. 

With advancements in data collection speed, 

accuracy, and interpretation, LiDAR has the 

potential to further improve the efficiency

The World of GNSS-Based Road Pricing 

Berg Insight, IoT market research 

provider, has released a new study all 

about GNSS-based road pricing. This 

type of road pricing involves charging drivers 

using special sensors called global navigation 

satellite systems (GNSS) that are inside their 

vehicles. Road pricing includes different 

schemes like electronic toll collection (ETC), 

road user charging (RUC), vignettes, and 

congestion charging. 

The installed base of GNSS-based on-board units deployed for road user 

charging exceeds 7 million units worldwide | Image: courtesy 

More than a dozen countries worldwide have 

GNSS-based RUC/ETC systems already up 

and running or getting ready to launch soon. 

Most of these systems are in Europe, but 

there are also programs in North America and 

Asia-Pacific. According to Berg Insight, there 

were over 7.4 million GNSS-based on-board 

units for road user charging in use around the 

world in 2023. And that number is expected 

to grow to almost 10.6 million units by 2028, 

with a growth rate of 7.3 percent. 

Berg Insight has identified Russia, Germany, 

and Poland as the biggest markets for 

GNSS-equipped vehicles used for road user 

charging. Russia leads the pack with over 1 

million on-board units for the Platon ETC 

system. Germany and Poland follow with the 

Lkw-Maut and e-TOLL systems, respectively. 

Other countries with over half a million onboard 

units include Belgium, Hungary, and the 

Czech Republic. 

Bulgaria and Slovakia also have hundreds 

of thousands of on-board units in use. New 

Zealand and Switzerland are also in the 

top 10 markets with their eRUC and LSVA 

systems. In the US, there are a few state-level 

RUC programs, but the country just misses out 

on the global top 10 list. 

GNSS-based road pricing is a growing trend 

around the world, with more and more 

countries implementing these systems to 

charge road users.

Enhancing 

Construction Site Safety 

with GNSS Systems 

Implement Construction Site Safety Practices 

Construction sites can be hazardous 

environments, with numerous 

potential risks to both workers 

and the public. It is vital for construction 

companies to prioritize safety and take 

advantage of innovative technologies to 

minimize accidents and ensure a safe working 

environment that complies with safety 

regulations. According to the Occupational 

Safety and Health Administration (OSHA), 

construction accidents are responsible for a 

significant number of injuries and fatalities 

each year. Implementing effective safety 

measures not only protects workers but also 

reduces the financial burden associated with 

accidents, such as medical expenses and 

workers’ compensation claims. Additionally, 

prioritizing safety creates a positive work 

culture, boosting employee morale and 

attracting qualified personnel who value their 

well-being. In recent years, Global Navigation 

Satellite Systems (GNSS) have emerged as 

powerful tools to enhance construction site 

safety. 

However, according to David Lloyd – 

Managing Director at Step Global Pty 

Ltd, “When designing safety systems for 

construction sites, GNSS alone will not 

be good enough, the system needs to be 

augmented with another technology, such 

as Ultra Wide Band (UWB) for distance 

measurement and paired with a backend 

system that provides different levels of 

alertness for each asset.” 

Lloyd further elaborates that, “While GNSS 

technology provides accurate positioning 

data, its application in densely populated 

construction sites is often limited due to 

its inherent limitations in close proximity 

scenarios. This is where UWB technology 

shines. By integrating UWB with GNSS, 

construction companies can achieve 

unparalleled precision in distance measuring, 

particularly in confined spaces where 

traditional GNSS systems may falter. UWB 

excels at providing urgent alerts in real-time, 

enabling swift response to potential hazards 

and minimizing the risk of accidents.” 

Understanding GNSS Technology 

and Its Applications in 

Construction 

Global Navigation Satellite Systems (GNSS) 

refer to a network of satellites that provide 

positioning, navigation, and timing services. 

The most well-known GNSS system is the 

Global Positioning System (GPS). However, 

other systems, such as the Russian GLONASS, 

the European Galileo, and the Chinese 

BeiDou, also contribute to the overall GNSS 

network. 

In the construction industry, GNSS technology 

is utilized for a variety of purposes. One of 

its primary applications is real-time tracking 

and monitoring of critical variables, such as 

worker movements and equipment location. 

By integrating GNSS systems into construction 

machinery and personal protective equipment 

(PPE), companies can gain valuable insights 

into the location and status of their assets, 

enabling them to make informed decisions 

regarding safety protocols and resource 

allocation. 

Common Hazards in 

Construction Sites 


GNSS SYSTEMS 

Construction sites are rife with various 

hazards that can pose risks to workers’ 

safety and well-being. Some of the most 

common hazards include falls from heights, 

electrocution, struck-by accidents, caughtin 

or between accidents, and exposure to 

hazardous substances. These hazards can 

lead to serious injuries or even fatalities 

if proper safety measures are not in place. 

It is essential for construction companies 

to identify and mitigate these hazards to 

create a safe working environment for their 

employees. 

Benefits of Using GNSS Systems 

for Construction Site Safety 

Construction sites are inherently dangerous 

environments, with numerous potential 

hazards. It is critical for construction 

companies to prioritize safety to protect 

their workers and ensure compliance with 

safety regulations. Construction site safety 

not only prevents injuries and loss of life but 

also minimizes project delays, reduces costs, 

and enhances the reputation of construction 

companies. The use of GNSS systems in 

construction site safety offers numerous 

benefits that can significantly improve overall 

operations and minimize the risk of accidents. 

“There are several benefits to using GNSS 

technology on construction sites, increased 

production, higher quality, less mistakes and 

of course jobsite safety,” says John S. Taylor – 

Chief Operating Officer at SITECH Gulf Global 

Positioning Systems LLC. 

GNSS technology provides enhanced 

situational awareness by providing realtime 

data on worker locations, equipment 

movements, and potential hazards. This 

allows for proactive decision-making and the 

ability to quickly respond to any emerging 

safety concerns. 

GNSS systems can also facilitate improved 

communication between workers, supervisors, 

and other stakeholders. With the ability to 

track and monitor personnel and equipment, 

communication channels can be optimized, 

ensuring that everyone is on the same page 

regarding safety protocols and emergency 

procedures. 

“In fast-paced environments such as 

construction sites, timely communication of 

safety alerts is critical. Integrated GNSS-UWB 

systems should feature a multi-level alert 

system designed to address diverse safety 

scenarios effectively. From routine safety 

reminders to urgent stop with engine shut 

off signals, a system would deliver real-time 

alerts, keeping workers and equipment 

operators informed and empowered to take 

proactive safety measures,” recommends 

Lloyd. 

Implementing GNSS systems streamlines 

workflow management by providing 

accurate data on project progress, resource 

utilization, and potential bottlenecks. This 

helps construction companies optimize 

their processes, reducing the likelihood of 

accidents caused by rushed or inefficient 

operations. 

Best Practices for Implementing 

GNSS Systems in Construction 

Site Safety 

To effectively implement GNSS systems for 

construction site safety, these best practices 

should be followed: 

1. Conduct a thorough safety 

assessment: Before implementing 

GNSS systems, it is essential to conduct a 

comprehensive safety assessment of the 

construction site. This assessment will help 

identify specific safety needs and determine 

the most suitable GNSS system for the site. 

2. Choose the right GNSS system: There 

are various GNSS systems available, each with 

its own features and capabilities. It is crucial 

to select a system that aligns with the specific 

safety requirements of the construction 

site. Factors to consider include accuracy, 

durability, battery life, and compatibility with 

existing safety protocols. 

John S. Taylor Chief Operating Officer – SITECH Gulf Global Positioning 

Systems LLC 

3. Provide training and education: 

Proper training and education are essential 

for the successful implementation of GNSS 

systems. Workers should be trained on how to 

use the systems effectively and understand 

the safety protocols associated with them. 

Ongoing training and refresher courses should 

also be provided to ensure workers stay 

updated on the latest safety practices. 

4. Regularly monitor and analyze 

data: GNSS systems generate a wealth of 

data that can be used to identify patterns, 

trends, and potential safety risks. Construction 

site managers should regularly monitor 

and analyze this data to identify areas for 

improvement and make informed decisions 

regarding safety protocols. 

“With proper implementation of GNSS with 

UWB technology, construction companies can 



FEATURE 

significantly enhance safety standards on 

their sites. This integrated approach not only 

mitigates risks but also fosters a proactive 

safety culture, where workers and equipment 

operators are empowered to identify and 

address potential hazards in real time. As 

construction projects become increasingly 

complex, the adoption of advanced safety 

solutions becomes imperative, ensuring the 

well-being of workers and the successful 

completion of projects,” emphasized Lloyd. 

Common Challenges and 

Solutions in Using GNSS Systems 

for Construction Site Safety 

While GNSS systems offer numerous benefits 

for construction site safety, there are common 

challenges that companies may face during 

implementation. 

One challenge is the potential for signal 

interference or obstructions, which can impact 

the accuracy and reliability of GNSS systems. 

This can be mitigated by using multiple GNSS 

systems, such as GPS, GLONASS, and Galileo, 

to ensure redundancy and minimize the 

impact of signal loss. 

Another challenge is the initial cost 

associated with implementing GNSS systems. 

However, it is crucial to consider the longterm 

benefits and return on investment that 

can be achieved through improved safety, 

productivity, and efficiency. Additionally, 

choosing the right GNSS solution provider 

and negotiating favorable pricing can help 

mitigate the financial burden. 

With reference to Taylor, “Two of the main 

reasons accidents happen on jobsites is that 

there are a lot of people around very heavy 

equipment with limited visibility and operator 

distractions. With GNSS technology less 

people are needed to be in close proximity 

to the machines, obviously making them less 

vulnerable to injury from a machine. Another 

reason is that with automatic machine 

control the blades of a dozer or grader are 

controlled by computer and not the operators 

themselves thus they can pay better attention 

to what is going on around them and a 

greater chance of sighting people and other 

safety issues they might be at risk of not 

noticing.” 

Future Trends and Advancements in 

GNSS Technology for Construction 

Site Safety 

As technology continues to advance, there 

are several trends and advancements in GNSS 

technology that hold promise for further 

enhancing construction site safety. 

One such trend is the integration of 

augmented reality (AR) and virtual reality (VR) 

with GNSS systems. This combination allows 

workers to visualize and interact with realtime 

data in a more immersive and intuitive 

manner. For example, workers wearing AR 

glasses can see virtual safety perimeters 

overlaid on the construction site, providing 

real-time guidance and warnings. 

Conclusion: The Future of 

Construction Site Safety with GNSS 

Systems 

The use of GNSS systems presents a 

significant opportunity for construction 

companies to enhance site safety and 

protect their workers. By implementing 

best practices, such as conducting thorough 

needs assessments, providing training and 

education, construction companies can 

successfully integrate GNSS technology into 

their operations. 

While there may be challenges to overcome, 

including signal interference and initial costs, 

the long-term benefits of improved safety, 

situational awareness, communication, and 

workflow management far outweigh these 

challenges. 

“A robust backend system is the backbone 

of an integrated GNSS-UWB safety solution. 

Such a system must leverage GNSS position 

reports to estimate collision risks and 

communicate with assets accordingly,” says 

Lloyd. “The system must be able to categorise 

assets based on their type and assign specific 

safety zones tailored to their characteristics. 

This classification-based zoning approach 

ensures that safety measures are customised 

to address the unique risks associated with 

each asset, whether human or vehicular,” 

concludes Lloyd. 

Looking ahead, future trends and 

advancements, such as the integration of 

AR and VR, hold great promise for further 

revolutionizing construction site safety. 

By embracing these advancements and 

continuously seeking ways to leverage GNSS 

technology, construction companies can 

create a more secure and productive future 

for their workers and the industry as a whole.
