(2).Main function introduced
1.Automatic Identification System (AIS) function
Be able to the continuous autonomous receive and transmit the AIS data information.
Display AIS data around own ship when ships equipped with AIS equipment.
Static data including : MMSI, vessel name, call sign, IMO number, ship type, ship size,
The location of the GPS antenna, Flag, etc.
Dynamic data include : latitude and longitude, speed, heading, rate of turn , azimuth , distance.
Navigation data, including : condition of navigation , ship's draft ,dangerous cargo ,destination and estimated time of arrival.
When AIS target ship enter pre-setting range ,visual and audio alarm occur ,according to range varying sound changing.
Emergency information send and receive.
2.Alarm function
When ship speeds greater than 2 knots to enter own ship within the range of 0.1 to 10 nautical miles,
The red light blinks on main unit display, At the same time ,speaker alarm tone: "The direction × × degrees ,
× × nautical Target Approaching "Careful avoidance."
3.Target ship information display function
List of showing the target ship (range, azimuth and 9 ID)
Vector display the target ship (provide 1-100 nautical miles range selection)
The target ship displayed on Electronic chart
4.GPS navigation function
8.0-inch color LCD display, can display the coastline of the country charts, the Geographic Names Information data and
waypoints Routes and track setting, edit, and delete function.
Ship's position, speed, heading, course track, time and date display.
Waypoints, routes, tracks stored in the call.
Destination position, distance and estimated time arrival display.
Navigate arriving at the destination , course deviated alarm , alarm and prompt
10,000 waypoints can be stored 10,000 mark, 200 routes, 200000 track points.
