AIS Class-B (8.0-inch) 

(1).Main Functions

FT-8700 is a universal shipborne AIS equipment, It can exchange navigation and ship data with other ships and
shore stations. 
This device complies with the IMO MSC74 (69) Appendix 3.A.694.ITU-RM.137-3, and DSCITU-RM.825 
And in accordance with IEC61993-2 (type of test standards), IEC60945 (EMC and environmental conditions). 
FT-8700 consists of Transceiver units,display-control unit, VHF and GPS antennas and related accessories. 
Transceiver unit comprises a VHF transmitter, two TDMA receivers, a channel 70 DSC receiver, 
An interface, communication processor, built-in GPS receiver. 
2.Main information 
AIS provided automatic exchange of navigational information with other ship or shore station to ensure the safety of navigation .
2.1 Static Data 
Call sign and ship name 
MMSI (9 digit ID ) 
IMO number (if any) 
Length and Beam 
Ship Type 
Location of GPS antenna position on ship 
2.2 Dynamic Data 
Ship's position 
UTC (universal time coordinated) 
COG (Course Over Ground) 
SOG (Speed Over Ground) 
Navigation status ( manual input data / code) 
Rate of Turn ( if any) 
2.3 Voyage Data 
Dangerous Cargo 
Destination and ETA 
2.4 safety-related short message 

(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.
