Datasheet
Super Sub-Mini Transponder/Responder (SSM)
Description
Sonardyne’s range of Super SubMini Transponder/Responders
(SSMs) represent the latest design
developments in the acoustic
positioning of ROVs, towfish and
other subsea targets.
The Type 7970 Super Sub-Mini is
designed for deepwater applications
up to 4,000 metres and has a highpower directional transducer with an
acoustic output comparable to
Sonardyne's most powerful Compatt
transponders.
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. The unit's
'bilingual personality' mode
automatically senses the type of
positioning system interrogating it
and switches mode accordingly.
Key features
• Depth telemetry capability with
choice of 2,000 or 4,000 Metre
rated sensors
• 1,000 Metre rated SSM also
available
• Directional transducer with class
leading acoustic power output
• Channel selection via dual external
controls or serial data port by PC
• Long-life, fast charging NiMH
battery
• Compact and rugged design
In addition, Super Sub-Minis now
support more Sonardyne frequencies
and all HPR 300 and HiPAP®
channels.
The Type 7970 is available with
either 2,000 metre or 4,000 metre
rated depth sensors.
• Windows based software for test
and setup
