Sonardyne’s existing Wideband SubMini transponder (WSM) is typically interrogated by a responder trigger sent down the ROVs’ umbilical or a narrow band tone signal. In som situations, reverberation or multipath of the tone interrogation can cause interference problems. The new Sonardyne 8190 WMT is Sonardyne’s first mini-sized transponder. It is slightly larger than the WSM and provides full two-way Wideband interrogation and reply which completely mitigates interference from and to other users.
