AIS Shore Base Station

AIS Base Station Transponder

According to IMO recommendations, the AIS system is employed by Authorities to improve monitoring of maritime traffic and VTS (Vessel Traffic Services) operations.
This technology, based on the use of GPS (Global Positioning System) receivers, enables transmission of position information in an automated, safe and accurate fashion.
Moreover, the AIS integrates position information with static and dynamic data enabling full identification of vessels.
The ABS-1103 is an independent AIS base station conforming to relevant international regulations (ITU-R M.1371 and IEC 62320-1). Compliance with these standards has been certified by BSH.
The ABS-1103 can be easily integrated in a regional monitoring system according to the IALA Recommendation A-124.
The ABS-1103 can be equipped, upon request, with additional functionalities. The Secure mode functions, for example, can be used to stop the standard broadcasting of AIS messages and/or enable encrypted communications with selected AIS stations (e.g. WAIS equipped vessels).
