Datasheet
Wideband Mini Transponder (Remote Transducer Version)
Description
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 some
situations, reverberation or multipath
of the tone interrogation can cause
interference problems. The 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.
For use on ROVs, the WMT includes
responder trigger, an integrated
rechargeable Li-ion battery pack that
is charged from the ROV’s power
supply, and full RS232
communications enabling channel set
up, power and gain etc. to be
changed from the surface.
An On/Off switch helps to ensure
the internal battery is not discharged
when not in use. When an umbilical
trigger is not available, then the full
Wideband transponder mode
provides excellent USBL performance
from a small, lightweight package.
Key Features
Remote omni or directional
transducers are available for both the
WMT and existing WSM range.
These make installation on an ROV
easier as the remote transducer can
be installed where there is good lineof-sight and is easily replaced if
damaged.
• Li-ion rechargeable battery pack
The main body of the transponder
can then be installed within the ROV
frame where it is well protected from
damage.
• Choice of right-angle or straight
connector style
• Full two-way Sonardyne
Wideband®2 interrogation and
reply – mitigates any interference
and multi-path issues
• Mini size – lightweight and small
• Responder mode
• Pressure sensor fitted as standard
• Full RS232 control from the surface
• External On/Off switch
• Choice of standard cable lengths:
0.6 m or 3.0 m, custom lengths
available on request
• Field proven
