Key Terms 

GPS satellites 

Term 

Description 

The term is an acronym that represents the Global Positioning System, 

which is managed by the US Department of Defense to support its 

navigation aid system. 

DGPS 

The term is an acronym that represents the Differential Global 

Positioning System, which is a system to improve the position fixing 

accuracy by receiving the correction data with a beacon receiver for a 

given GPS satellite, which is transmitted by the beacon station with a 

known position. 

Position fixing 

The term means to obtain the current position of your vessel with the 

GPS or DGPS receiver. 

2D (Two-dimensional position fixing) 

The term 2D means the position fixing with data obtained from the satellites 

and antenna height information. 

3D (Three-dimensional position fixing) 

The term 3D means the position fixing with four or more satellites information 

only. 

HDOP 

The term is an acronym that represents the Horizontal Dilution of 

Precision, which reflects the position fixing accuracy. The accuracy 

increases as the value decreases. 

The value increases when the satellites are gathered close to each other, 

and it reduces when the satellites are spattered, which in turn means 

increased accuracy. 

Route plan 

This is the plan that consists of the multiple waypoints registered in the 

order of navigation. 

CDI 

The term is an acronym that represents the Course Deviation Indicator, 

which includes information on the deviation from a given planned course 

and direction to be steered. 

Arrival alarm 

The alarm notifies that your vessel has arrived at the preset distance 

from a given destination. 

Anchor alarm 

The alarm notifies that your vessel has drifted away from the destination 

by the preset distance. 

Off-course alarm 

The alarm notifies that your vessel has been deviated from the planned 

course by the preset distance. 

9


Boundary alarm 

The alarm notifies that your vessel has crossed a preset boundary line. 

Automatic sequencing mode 

The function automatically switches to the next destination after your 

vessel has entered the preset arrival alarm range of a previous destination 

point according to a route navigation plan. 

Manual sequencing mode 

The function allows the operator to manually change to the next leg of a 

route during navigation based on a route plan. 

Default values 

The values represented by the factory settings. 

NMEA 0183 

This is a standard specified by an international organization called the 

National Marine Electrical Association (NMEA) to specify the 

requirements for the data communications among various equipment. 

Master reset 

This function clears all the settings on the Processing Unit and the Display 

Unit . Note that all the settings will be cleared if the function is 

performed and reset to factory defaults. 

Initialization 

A maximum duration of about 3 minutes is required for position fixing if 

the equipment is to be operated for the first time after the installation or 

the master reset function has been performed. The initialization time 

can be reduced for position fixing by manually entering the estimated 

position, time, and antenna height. 

Course 

A direction made good, obtained by connecting the positions tracked by 

the vessel, which is mainly the direction displayed by the GPS. 

Bearing (Heading) 

An angle formed between the local meridian and the orientation of the 

bow during the navigation, which is mainly displayed on the GPS compass 

(this unit), gyro compass or magnetic compass. 

10


1. Equipment Overview 

1.1 Functions 

This unit determines the heading of the ship by measuring the orientation between two antennas using the 

signal from the GPS satellites. 

It is not only possible to measure the heading with a high accuracy continuously for 24 hours all over the 

world and in all weather conditions using the GPS satellites, but also it measures the position. And when the 

DGPS beacon receiver is connected the measurement accuracy of position can be further enhanced by receiving 

the correction data from the DGPS beacon station. 

Since this unit outputs the bearing information at high speed, if this unit is connected to Radar units JMA- 

3800 or JMA-3900 manufactured by our company, it is possible to fully take advantage of the Radar and ARPA. 

11


1.2 Features 

This unit has the following features: 

• JRC specific dual antenna method 

A dual antenna method that as applied has excellent bearing precision and reception rate, and can be 

easily installed. 

• Low maintainance 

Unlike a gyro compass, this unit does not require as often as inspection or as much maintainance. 

• Can be used soon after switching ON the power. 

The measurement of heading can be done from about 3 minutes (standard value) after switching ON the 

power. 

• Excellent tracking capacity 

The tracking capacity is much better than that of a gyro compass. 

• Can be connected directly to a JRC Radar. 

Since this unit outputs the data to the JRC Radar at a high speed, it is possible to fully bring out the 

performance capabilities of the Radar and any ARPA functions. 

• Output of the orientation, position, and speed data. 

This unit also has the functions of a GPS receiver. 

• Synchronization signal can be output (optional). 

It is possible to connect a synchronous type repeater using the optional interface. 

• Large-sized dot matrix LCD display with back light. 

A screen that is easy to see and has a large amount of information can be displayed because of the use of 

a large-sized LCD display. Both the keyboard and display are provided with a back light, so night operation 

is no problem. 

• Graphic display 

In the CDI display mode, the direction in which the ship has to be steered can be easily seen, thereby 

helping for efficient fuel saving navigation. 

In the plot display mode, it is not only possible to display the path that has already been traversed but also 

possible to display the symbols registered beforehand for the different destinations. 

• Menu selection method makes operation easy to grasp. 

From the menu display on the screen, it is possible to understand the selections intuitively, thereby making 

the operation easy. Selection and confirmation of the menu is done using a dial which is very easy to 

operate. 

• Customizing 

Since a variety of setting items have been provided, it is possible to create a navigation system with the 

preferences of an individual user. 

• One-touch display installation and removal. 

The Display Unit can be easily removed from the frame by pressing the button at the back of the Display 

Unit. 

• Seven languages are supported. 

12


1.3 Configuration 

This configuration consists of the three units of the Antenna, the Processing Unit, and the Display Unit. 

Further, a Digital/Synchro Converter unit for a repeater (GPS repecon), a DGPS receiver and a DGPS 

beacon receiver can be connected as optional.

3. Installation 

3.1 Installation of the Antenna 

3.1.1 Choosing the Location 

CAUTION 

When connecting the cable attached to the equipment, do not bend it to an 

acute angle, twist it, or impart excessive force. Cracks or damage to the 

coating can cause a fire or electric shock. 

Do not install the antenna where there is excessive vibration. 

Accidents can be caused by receiving poor. 

Install the antenna where there is no viewing obstacle, in order to ensure that 

GPS signals can be directly received from satellites without interference or 

reflection of signals from surrounding objects. 

Whenever possible, select a place having the following characteristics. 

1. An open space which allows uniform reception of satellite signals. 

2. Far away from any high power transmission antennas. 

3. Outside of any radar beams. 

4. Away from the inmarsat antenna by at less 5 meters and below the level of its 

antenna. 

5. Away from the antenna of a direction finder, VHF or MF/HF by 5 meters or 

more. 

6. Away from a magnetic compass by at least 1 meter. 

If it is difficult to find an ideal site, select a place temporarily and install the antennas. 

Conduct a test to make sure that the proper performance can be obtained and then fix 

the antenna in position. If it is installed at an improper place, bearing accuracy is poorer, 

and accidents can be caused.

3.6 Measures for the Electromagnetic Interference 

The equipment needs to be installed properly in order to ensure its successful operation even though it has 

been designed to satisfy the requirements stipulated by the electromagnetic compatibility (EMC) requirements. 

Several factors that can affect the equipment performance are shown below. 

3.6.1 Checks before the Connection 

Observe the following instructions to avoid possible electromagnetic interference when connecting a cable 

(Antenna, Display unit, Radar or Power supply cable) to the equipment. 

• Keep this equipment away from another equipment (minimum of 1 meter) that is transmitting high frequency 

signals or any cable transmitting such signals. Some examples of such equipment include the VHF transmitter 

and receiver and antenna cable. Keep a minimum distance of 2 meters in the case where the equipment 

needs to be installed near a SSB transmitter/receiver. 

• Keep the equipment away from the radar beam by a minimum of 2 meters. 

In general, for this purpose, the radar beam is understood to be covering from its source in the range of 30 

degrees above and below its center axis (a total of 60 degrees). 

• Do not use the same power supply to start the engine as the power supplied for this equipment. 

The equipment may be reset if its power supply voltage drops below DC 10V, which in turn may result in the 

loss of some data or change in the operation mode even though the equipment itself will not be damaged. 

• Use only the cables specified by us. The cable may fail to satisfy the EMC performance requirements if it is 

cut or reconnected after cutting. Thus, the cable should never be tampered with unless otherwise specified

4.19 Setting Route Plans 

A route consisting of several connected waypoints is called a route plan. For example, say that you go from a 

harbor (waypoint number 010), to a fishing point (waypoint number 011), to another fishing point (waypoint 

number 012) and then return to a different harbor (waypoint number 013). 

Fishing point 

Harbor AA (waypoint number 011) 

(waypoint number 010) 

Fishing point 

(waypoint number 012) 

Fig. 4-9 

Harbor BB 

(waypoint number 013) 

This route plan thus consists of harbor AA and the destinations which are the two fishing points (waypoint 

numbers 011 and 012) and harbor BB (waypoint 013). In following a set route plan, the navigator switches from 

one waypoint to another when it comes within a certain distance of the first waypoint (automatic stepping) or by 

manually stepping to the next waypoint. 

• For information on entry operations given below, see Section 4.6, “Basic Menu Selection Operations.”
