Type 7973 Super Sub-Mini (SSM) is depth 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 the popular acoustic navigation systems.
