(1),Main Functions 
1,Automatic Identification System (AIS) function 
Be able to the continuous autonomous receive and transmit the AIS data information.
Can 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 GPS antenna position, Flag, etc.
Dynamic data include: latitude and longitude, speed, course, rate of turn ,heading, azimuth, distance. 
Navigation data, including: condition of navigation, ship' 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,AIS target Approaching, sound (audio) and light (visual) 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 
10.4-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, track, store and call. 
Destination position, distance and estimated time arrival display. 
Navigate arriving at the destination , course deviated alarm , alarm and prompt.
