AIS Tester is a test device operating on AIS1 (ch87B), AIS2(ch88B) and DSC(ch70) frequencies. The tester is designed under corresponding standards and recommendations as a tool of operation and installation tests of AIS unit (Automatic Identification System).  The tests’ volume comply with “Guidelines on annual testing of the AIS unit MSC.1/Circ.1252”.

Tester does not use a GPS for synchronization. A proprietary TDMA slot-synchronizing algorithm is used which does not require a GPS 1 pps.  It uses RATDMA for generating VDL and interrogation messages. A Pilot Plug evaluation function and NMEA/RS422 terminal display of external sensor inputs is provided.
