Automatic Identification System
Kongsberg Seatex provides, via its AIS 200 mobile station, a technical solution that enables the identification of other vessels and navaids fitted with the VHF based AIS technology. This can be either on a stand-alone display or on the ship’s electronic chart and radar. The ability to view and identify all vessels and their courses and speed, is a major contribution towards safer navigation for the maritime community.
GPS Position Interface
The vessel´s primary GPS receiver needs to be interfaced with the AIS and is used as the main positioning source. However, the AIS 200 also incorporates an ”allin- view” GPS receiver which can be used as back up for the primary GPS receiver.
Heading Interface
Vessel heading as derrived from the gyro compass needs to be interfaced to the AIS. This may require a gyro converter if the heading output from the gyro compass is a stepper or synchro signal and not a serial line signal which uses the NMEA data protocol for data exchange.
Easy installation
The remotely installed transceiver with separate display provides a simple installation solution, saving time and money.
AIS Minimum Keyboard Display
The AIS 200 MKD with a 4 line display is delivered as standard. However, this display unit may be replaced by a larger display (AIS 100 MKD) that additionally provides graphical display of received AIS targets.
VHF data communication
Dedicated VHF frequencies are used for AIS data communication and the range is dependant on the height of the VHF antenna. In order to avoid interference with the ship’s VHF voice communication, the AIS VHF antenna must be installed in accordance with IMO requirements.
As the SOTDMA (Self Organized Time Division Multiple Access) protocol, which utilizes time-slots for transmission and reception of data is being used, an almost unlimited number of users may operate on the system at the same time without causing interferance problems.
Chart and Radar Interfacing
AIS can be interfaced to electronic charts or radar provided they support the AIS interface. When interfacing AIS to radar and chart plotters, AIS target information as position, heading course and speed becomes available to the mariner and increase reliability of received navigation data from other vessels.
