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 suitabl e mounting location for the antenna unit.

•

The antenna may be mounted three ways: screwed into a pip e (local supply), fixed to a post with the optional mast m ount ing 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 minim um separation distances fr om other antenna units.

Mounting procedure

Install the antenna unit by referring to t he installation diagram on page D-1.

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 to four extension cables can be connected serially.

Connecting to FURUNO NavNet equipment

Connect the antenna cable to the DATA1 port on NavNet equipment.

Antenna Cable 10 m

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 t he power and the n 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.
