Sonardyne 7973 SSM

Sonardyne’s range of Super Sub-Mini Transponder/Responders (SSMs) represents the latest design developments in the acoustic positioning of ROVs, towfish and other subsea targets.

 

The Type 7973 Super Sub-Mini isdepth rated to 1,000 metres and has an omni-directional beam pattern that gives a wide area of acoustic coverage.

 

For improved positioning accuracy, a built-in pressure transducer provides depth; this can be telemetered to Sonardyne’s USBL systems as part of the positioning cycle. A dual external channel selection control, or serial data link, allows the SSM to be used with all of the popular acoustic navigation systems.

 

The unit’s ‘bilingual personality’ mode automatically senses the type of positioning system interrogating it and switches mode accordingly. In addition, Super Sub-Minis now support more Sonardyne frequencies and all HPR 300 and HiPAP® channels.

 

Options for the Type 7973 SSM include a remote transducer that provides added flexibility when sitting the unit on smaller vehicles and a floatation collar to enable seabed deployment.
