Datasheet
Super Sub Mini Transponder/Responder (SSM)
Description
Sonardyne’s range of Super Sub-
Mini Transponder/Responders
(SSMs) represents the latest design
developments in the acoustic
positioning of ROVs, towfish and
other subsea targets.
The unit's 'bilingual personality'
mode automatically senses the type
of positioning system interrogating it
and switches mode accordingly. In
addition, Super Sub-Minis now
support more Sonardyne frequencies
and all HPR 300 and HiPAP®
channels.
The Type 7973 Super Sub-Mini is
depth rated to 1,000 metres and has
an omni-directional beam pattern
that gives a wide area of acoustic
coverage.
For improved positioning accuracy, a
built-in pressure transducer provides
depth; this can be telemetered to
Sonardyne's USBL systems as part of
the positioning cycle. A dual
external channel selection control, or
serial data link, allows the SSM to be
used with all of the popular acoustic
navigation systems.
Options for the Type 7973 SSM
include a remote transducer that
provides added flexibility when
sitting the unit on smaller vehicles
and a floatation collar to enable
seabed deployment.
