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. CBAS provides GPS signal corrections to SBAS
users, for even better position accuracy, typically better than three meters. There are three more
SBAS providers, MSAS (Multi-Functional Satellite Augmentation System) for Japan, EGNOS
(Euro Geostationary Navigation Overlay Service) for Europe and GAGAN (GPS And GEO
Augmented Navigation) for India. The illustration below shows the coverage area. (Accuracy
may be affected when using a GEO satellite not within your current location.) This manual uses
“WAAS” for these three providers generically.

1. MOUNTING
NOTICE
Do not apply paint, anti-corrosive
sealant or contact spray to coating or
plastic parts of the equipment.
Those items contain organic solvents that
can damage coating and plastic parts,
especially plastic connectors.
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 directl y. 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 t o f our
extension cables can be connected serially.
Connecting to FURUNO NavNet equipment
Connect the antenna cable to the DATA1 port on NavNet equipment.

4. TROUBLESHOOTING, BATTERY
Troubleshooting
If the message “No position data” appears on the displa y 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 interf ere with recep t ion.
2) Check that the antenna cable is firm ly fast ened.
3) If extension cable(s) are used, check for water leakage at junct ion point(s).
4) Check the antenna cable for damage.
5) Check the antenna for damage.
If the problem seems to be with the antenna ca ble 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.
