270 kHz |
The system consists of two transducer elements installed in the ship's keel. The transducers can alternatively be used, e.g. one is backup. Electronic cabinet is mounted in Gravitymeter Room F-632. Hydroacoustic frequency amounts to 270 kHz. Transducer 1 S/N: 17889; Transducer 2 S/N: 17895. |
Time synchronising is regulated by DShip. Geographical ship's position is provided by DShip. |
Data storage in DShip system. |
