Description

Sonardyne’s existing Wideband Sub- Mini transponder (WSM) is typically interrogated by a responder trigger down the ROVs’ umbilical or a narrow band tone signal. In some situations, reverberation or multipath of the tone interrogation can cause interference problems. The new WMT is Sonardyne’s first mini-sized transponder, slightly larger than the WSM and providing full two-way Wideband interrogation and reply which completely mitigates interference from other users and to other users. For use on ROVs, the WMT includes responder trigger, an integrated Li-Ion battery pack that is charged from the ROV’s power supply and full RS232communications enabling channel set up, power, gain etc. to be changed from the surface. An On/Off switch helps ensure the battery pack is not discharged when not in use. When an umbilical trigger is not available, then full Wideband mode provides excellent USBL performance in a small, lightweight form. New remote transducers, either omni or directional are available for both the WMT and existing WSM range. These make installation on an ROV easier as the transducer can be installed where there is good line-of- sight. The main body of the transponder, the more expensive part, can then be installed within the ROV frame where it is well protected. Transducers can then be easily replaced if damaged. Key Features
