Datasheet
Dynamic Positioning Transponder (DPT)
Description
The Types 8124, 8126 and 8129
DPT’s are full sized transponders
designed specifically for seabed
deployment or large target tracking.
Key Features
•
3,000 or 7,000 metre depth rating
•
Omni, Directional or Super
Directional transducers
•
Incorporates Sonardyne’s latest
Wideband™ Technology
•
Multiple operating modes; tone
burst and wideband
•
Hundreds of operating channels
allowing truly independent acoustic
operations
•
Highly reliable release mechanism
•
Standard Sensors - depth &
temperature
•
Easy to set-up and test using PC
software, PTT or DTU
•
Responder Operation
•
Accepts external DC power
DPTs support Sonardyne
Wideband™ signals, tone
frequencies and all HPR
300/HiPAP® channels. DPT also
supports Sonardyne command and
control options.
•
Long battery life
•
Midi housing option available
(Type 8129)
Available in 3,000 metre rated omni-
directional or directional transducers,
DPTs are equipped with a rugged
spring assisted release mechanism,
depth sensors and advanced power
and gain controls if required.
For deep-water towfish tracking, the
Type 8129 DPT is a midi-sized unit
with a high power super directional
transducer that is depth rated to
7,000 metres.
Also available is the Type 8132
DPTi which is fitted with internal
inclinometers to accurately monitor
riser angles (see separate datasheet).
The DPTi can also be used with an
external inclinometer unit to monitor
flex joint angles.
