AIS Class-B (12.1-inch)

(1). Main function introduced

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 include: MMSI, vessel name, call sign, IMO number, type of ship, 
The size of the vessel, the GPS antenna position, Flag, etc. 
Dynamic data include: latitude and longitude, speed, heading, rate of turn , 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 
Send and receive emergency information by Chinese or English 
AIS fleet management, AIS ship against alarm and found the ship list of alarms set; 
AIS target ship's basic data display (ship name , id no , flag…..etc.),tracking record 

2.AIS target Approaching, sound (audio) and light (visual) alarm function 
Distance alarm : When AIS ship enter within setting range of own ship, sound and light alarms will start 
CPA alarm: When AIS ship enter TCPA, DCPA's alert setting area , sound and light alarm will start . 
Note: while alarming, AIS targets on the screen turns red icon, flashing alarm indicator on the front panel, 
At the same time speaker alarming tone: "The direction × × degrees apart × × nautical target Approaching
Careful avoidance." 

3.Target ship information display function 
List of showing the target ship (range, azimuth and 9 ID) 
Target ship can display on Radar chart (display range of 1-128 nautical miles) 
Target ship can display on Electronic chart 

4.GPS navigation function 
Can display the coastline of the country charts, the Geographic Names ,river map, and beacon lights , dangerous object 
Ship's position, speed, heading ,course, track, time, date, and fishing areas display; 
Beacon lights, hazardous materials increased add-on editing features; 
Cursor position can read tides, port information, calendar, satellite images show the function; 
Waypoint marker points, routes, track line storage and call 
Can store up to 8000 waypoints, 10,000 mark point, 1000 route 100 000 track points 
Cursor, waypoints, routes, track line navigation functions; 
Destination position, distance and estimated time arrival display 
Has arrived, course deviated , and take the anchor, speeding, route steering, the bridge alarm and prompted
