LRIT COMPLIANCE<br />
Notes on the LRIT system<br />
• Power the equipment and keep it logged in at all times except for special occasions<br />
such as when the ship is dry-docked for repairs. Position information is automatically<br />
sent at fixed intervals, thus no operation is required. However, keep the equipment in a<br />
ready state to received commands from the LRIT data center. Combined use for routine<br />
messages, distress messages and SSAS (Ship Security Alert System) is possible.<br />
• The source of position data for this equipment can be its internal GPS receiver or<br />
external GNSS (Global Navigation Satellite System) equipment. For GNSS equipment,<br />
interface directly to the shipborne global navigation satellite system equipment.<br />
• If external GPS equipment is used, set it to use WGS84 datum. Further, the output<br />
sentences should minimally be as follows:<br />
- Time data input: ZDA<br />
- Position data input: RMC or GGA and VTG (pair)<br />
• This equipment and external GNSS equipment must be powered in the following<br />
manner.<br />
- If the above equipment is to be used as a GMDSS device also, connect them to an<br />
auxiliary power source (radio communications battery).<br />
- If the above equipment will not be used as a GMDSS device, connect them to both<br />
main and emergency power sources (via AC-DC power unit PR-240).<br />
• If an error message appears, take the necessary measures to restore normal operation<br />
as soon as possible. Shown below are representative alarms.<br />
- WARNING: External NAV equipment failure.<br />
Position data is not correctly input from the external GNSS equipment. Check the<br />
GNSS equipment and the wiring between it and the <strong>FELCOM</strong>.<br />
- WARNING: Internal GPS UNIT failure.<br />
Position data is not correctly input from the internal GPS receiver. If this alarm occurs<br />
frequently, have the set checked.<br />
- WARNING: Synchronization loss. Please check the current Ocean Region. -<br />
- WARNING: BBER over 80%. Scanning NCS start manually.<br />
Problem with receiving the Inmarsat-C signal. Check if the current sea area is<br />
suitable for your position. If it is not, change the sea area. If the area is suitable and<br />
the alarm continues, check the antenna and antenna cable. Request service if the<br />
problem persists.<br />
