AIS Shore Station


AIS Shore Station

Rack Mount AIS Shore Station

i-ais-BS1 is an AIS station designed for AIS management and monitoring functions to be performed with a shore installation.

i-ais-BS1 AIS Shore station consists of an AIS Unit for standard AIS functions and a Communication Gateway to be able to communicate with an operation center over IP connectivity.

i-ais-BS1, AIS Shore Station, is mainly used to monitor the AIS VDL network around and to provide support for proper messaging with Class-B transponders with mission specific functions.

  • Monitoring of AIS network
  • Transmission of AIS messages (6, 7, 8, 12, 13, 14)
  • Reception of all AIS messages (1 to 27)
  • Text messaging with ships (Msg 12 and 14)
  • Encrypted binary messaging (Msg 6 and 8)
  • Optional mode to send raw AIS NMEA data (non-encapsulated) over TCP/IP connection

  • Transmission and reception of mission specific Class B messages
  • Standard 19” 3U form factor for rack installation
  • 2 x RS-232 Ports for NMEA, 1 x RS-232 Port for AUX, 1 x ETH port for ADSL, D-IN (Digital Input)
  • Compatible with i-SEA Platform
  • Remote management (through Ethernet or GPRS)
