[email protected] www.sonardyne.com Datasheet Wideband Sub-Mini Transponder/Responder (WSM) Description Sonardyne’s family of Wideband Sub-Minis (WSM) are a versatile range of USBL transponder/ responders designed for positioning ROVs, towfish and other mobile targets in water depths up to 3,000 metres. Compact and rugged, WSMs incorporate the latest Sonardyne Wideband® signal technology which offers superior ranging accuracy, operation in a mulit-user, multi-vessel environment and fast USBL position updates. In addition to supporting new Sonardyne Wideband® signals, WSMs also support traditional Sonardyne tone and HPR 300 and HiPAP® channels. A link allows the WSM to be configured for use with all of the popular MF frequency acoustic navigation systems. The Type 8071 WSM is equipped with an omni-directional transducer and is depth rated to 1,000 metres making it suitable for a wide ranger of general USBL tracking application. The Type 8070 WSM is a 3,000 metre rated unit and features a highpower directional transducer with an acoustic output comparable to Sonardyne's most powerful full size seabed transponders. Both types of WSM have a depth sensor fitted as standard to aid USBL positioning accuracy and an external On/Off switch for ease of use and storage when not in use.
