Block diagram of the AIS System
The AIS Electronics Unit contains a VHF radio, a GPS receiver and a Mainboard with the interfaces. The
AIS Electronics Unit has three inputs for the essential ship’s sensor data such as position, speed and
heading. These data are supplied by means of the navigation system such, as a RADARPILOT 1000.
The AIS communicates with the navigation system via the primary display port and/or the Ethernet LAN.
In this way the AIS is supplied with additional data such as the ship’s data, administration data and
configuration data.
The ship’s data, the ship’s sensor data and the position data (from external or internal GPS receiver) are
transmitted via VHF.
In the opposite direction, the corresponding data of other ships equipped with AIS systems are received
by means of the VHF receiver. These data are processed and sent to the navigation system via the
primary display port or the Ethernet LAN.
The functions of the pilot port correspond to the functions of the primary display port, but the pilot port
must be made accessible for pilots on the ship’s bridge. It must not be used for other purposes.
