Datasheet
OBC 12 Transceiver
Description
The Type 7911 transceiver used by
Sonardyne's TZ/OBC positioning
system has a remote transducer
which is generally deployed in an
over the side arrangement, or
through hull.
On command from a PC equipped
with Hydropos software, the
transceiver interrogates the seabed
transponders and simultaneously take
in DGPS information. This raw data
is then processed in real time to
produce ground station positions to
better than 2 metres absolute. Raw
data can also be output to the client’s
own navigation processor for
independent final network
adjustment.
Key features
• Can receive all 9 replies from a
group of transponder
simultaneously
• Can interrogate all 401 VLCT
address groups
• Shock mounted internal electronics
• Remote transducer and submersible
transceiver provides maximum
flexibility during mobilisation
• Plugs directly into Concept systems
Gator system, or used with
Hydropos
• High quality AG&G connectors for
power, comms and remote
transducer
