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.
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 high-
power directional transducer with an
acoustic output comparable to
Sonardyne's most powerful full size
seabed transponders.
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.
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.
