SYSTEM OVERVIEW
The GP-320B is a GPS receiver with WAAS (Wide Area Augmentation System) capability.
WAAS, available in North America, is a provider in the worldwide SBAS (Satellite Based
Augmentation System) navigation system. An SBAS provider furnishes GPS signal
corrections to SBAS users, for even better position accuracy, typically better than three
meters. Two more SBAS providers are also currently under development, MSAS
(Multi-Functional Satellite Augmentation System) for Japan and EGNOS (Euro
Geostationary Navigation Overlay Service) for Europe. All providers will be compatible with
one another, thus providing “seamless” position fixes to SBAS users.
SBAS is currently in the developmental phase and SBAS providers are expected to have
initial operations capability from the times shown below. During the developmental phase
the reliability and availability of the SBAS signal cannot be guaranteed.

1. MOUNTING
Mounting considerations
Follow the guidelines below to choose a suitable mounting location for the antenna unit.
• The antenna may be mounted three ways: screwed into a pipe (local supply), fixed to a
post with the optional mast mounting kit, or screwed into an optional mounting base. For
fixing by the post or pipe, it is recommended to use stays to prevent damage to the GPS
receiver.
• Select a location out of the radar beam. The radar beam will obstruct or prevent
reception of the GPS signal.
•
The location should be well away from a VHF antenna. A GPS receiver is interfered by a
harmonic wave of a VHF antenna.
•
The location should be well away from an Inmarsat antenna. Inmarsat transmission will
obstruct or prevent reception of the GPS signal.
•
There should be no interfering object within the line-of-sight to the satellites. Objects
within line-of-sight to a satellite, for example, a mast, may block reception or prolong
acquisition time.
•
Mount the antenna unit as high as possible to keep it free of interfering objects and
water spray, which can obstruct reception of the GPS signal if the water freezes.
•
Observe the following minimum separation distances from other antenna units.

2. WIRING
This unit outputs position and speed to external equipment. NavNet equipment, Multi
Display RD-30 and Echo Sounder LS-6100 can be connected directly. For connection to
other equipment, use a junction box (local supply) which has seven terminals.
The antenna cable is 10 meters long. If the distance between the antenna unit and the
display monitor is more than 10 meters, use the optional cable assy. (10 m). Up to four
extension cables can be connected serially.
Connecting to FURUNO NavNet equipment
Connect the antenna cable to the DATA1 port on NavNet equipment.

If you use the cable assy.(s), waterproof their connectors by wrapping them with vulcanizing
tape and then vinyl tape. Bind tape ends with suitable cable-ties.

Note 1: When connecting FURUNO DGPS beacon receiver GR-80 to this unit, set it as
follows:
Byte Format, 8-6; First Bit, LSB; Parity Bit, None; Stop Bit, 1; Bit Rate, 8.
Note 2: The signal ground and frame ground are separated, however the power line is not
isolated. Therefore, do not connect the signal ground to the frame ground when
other equipment is connected to a positive ground battery.
Note 3: WAAS function is inoperative when wiring as shown above.

4. TROUBLESHOOTING, BATTERY
Troubleshooting
If the message “No position data” appears on the display of NavNet equipment, there may
be a problem with the GPS receiver. Turn off the power and then check the following points:
1) Check for objects around the antenna which may interfere with reception.
2) Check that the antenna cable is firmly fastened.
3) If extension cable(s) are used, check for water leakage at junction point(s).
4) Check the antenna cable for damage.
5) Check the antenna for damage.
If the problem seems to be with the antenna cable or antenna, contact your dealer.
Battery
The antenna unit contains a lithium battery which preserves data when the power is turned
off, and its life is approximately 20 years (operating rate 70%) for large vessels and 10
years (operating rate 20%) for small vessels. The equipment can be used when the voltage
of the battery is low, however data is not backed up and the unit starts up in the “cold start”
condition.
