AIS Aids to Navigation (AtoN) is the latest application of AIS technology. The AIS AtoN transponder can be installed in lighthouses, lanterns, buoys, other fixed and floating Aids to Navigation, or offshore platforms to achieve greater functionality by monitoring and broadcasting their status and other information. There are three types of AIS AtoN:

● Type 1 - no receiver (transmitter only) using ATDMA.

HEA851 B-AIS is a new version of marine navigation Automatic Identification System designed by HHEE independently. The integration with information processing, VHF radio data transfer and GIS enables HEA851 to achieve the information transfer and display from ship to ship and ship to coast, which is so important to the safety for a ship on voyage.

The Raymarine AIS250 Receiver module is a 'listen only' AIS receiver that easily integrates with an existing VHF antenna using a built in VHF splitter. The AIS250 then interfaces to Raymarine multifunction displays, allowing AIS targets to be graphically overlaid in both the chartplotter and radar modes.

Use CSTDMA technology. 。 This technology is widely used internationally AIS Class B standard, especially for China, the truth.

- Can be used with any international standard AIS ship station (A type and B type), AIS-SART, base stations, beacons AIS communicate with each other.

 - Time to send the ship static and dynamic data, feel free to send the default security information.

- Full channel design.

- Frequency, the work area can be controlled by the base station by remote command switch. And island areas in the river can have the use of the desired results.

The Nauticast™-B Automatic Identification System (AIS) from ACR Electronics is a Class B transponder that is designed to bring you the best in bridge electronics. The Nauticast™-B offers a great value and an excellent feature set. The Nauticast™-B is a black box solution that comes to you as a compact, all-in-one kit, providing you with space savings and simplicity. The kit includes both VHF and GPS antennas and ACR’s Link2AIS™ Software. The Link2AIS™ Software may be installed on an onboard PC, or third party software that is AIScapable may be used. The Nauticast™-B also can be interfaced to chart plotters/Multi Functional Displays (MFDs) which display targets

- To receive any international standard AIS ship station (A type and B type), AIS-SART, base stations, beacons transmit AIS data.

- May be subject to remote base station.

- Such as the installation of built-in GPS module, can handle the RTCM signal received AIS base station sends RTCM statement, you can get DGPS function.

- Excellent RF performance, high receiving sensitivity.

- Wide input range DC power supply.

- Has three output interface, RS232, RS422 and LAN. Adapt to a variety of purposes.
