AIS BS610

The AIS Base Station is the primary component in an Hot stand-by AIS Physical Shore Station (PSS), and therefore the most vital component in a coastal AIS network. The AIS BS610 receives and communicates AIS data from all AIS sources: AIS mobile stations, other AIS Base Stations, AIS Aids to Navigation units, Search and Rescue units etc, within the VHF coverage area. In order to obtain a very high level of service and availability, a redundant base station configuration can be established. Two AIS BS610 units will operate autonomously in such a configuration when connecting them with a 0-modem cable and enabling the redundancy functionality. In case of an automatic change in redundancy status, the control centre will be notified.

The AIS system provides a valuable tool to increase the situation awareness, the efficiency of operations and safety. Experience shows that the workload for operators involved in vessel tracking and monitoring is considerably reduced after the introduction of AIS. Kongsberg Seatex has also developed satellite based AIS receivers and this space-based AIS technology has strong focus on receiver sensitivity. The high sensitivity has been incorporated in the AIS BS610. The increased sensitivity exceeds the requirements in international standards and regulations, and is an incredible enhancement in terms of signal reception. The AIS BS610 has an Ethernet/LAN interface, making it easy to interface the base station to other equipment or data networks. From the AIS Central Monitor Application Suite a single AIS BS610, or a network of base stations, can be remotely operated and maintained. The AIS BS610 also supports configuration and firmware upgrade via a web interface. All base station functions can be configured and effectuated remotely via this interface.

The AIS BS610 is able to broadcast DGNSS corrections through the standardized AIS message 17. Hence, differential corrections can be transmitted to all vessels which carry an AIS mobile station if the vessel is located within the base station’s coverage area. The AIS BS610 boosts its functionality with a VHF antenna and supports various power configurations and interfaces for operational flexibility. It also features RTCM v.2.3 support for reception of DGPS corrections on LAN, and can manage three remotely configurable receivers (TDMA/DSC). Other functionalities include USB interface for firmware upgrades, transmission of virtual AtoN, and AIS repeater functionality in accordance with IEC 62320-3. It also offers redundancy support and can support 10 parallel consecutive TCP connections.
