The transponder has been
developed to allow a user to precisely position a structure
or load on the seabed and then release it on command using
a Sonardyne Long BaseLine or Ultra-Short BaseLine acoustic
navigation system. The need for a separate back deck unit
to control the acoustic release is therefore removed, saving
operational time and money.
All Medium Frequency Compatt
5s now incorporate Fusion Wideband Technology which uses
advanced digital signalling techniques to dramatically improve
the performance of acoustic positioning, navigation and
telemetry systems.
The faster and more rugged
wideband telemetry scheme supported by Compatt 5, enables
baseline measurement and calibration data to be acquired
faster and more reliably, allowing users to begin work sooner.
Standard features include
the choice of standard or short housing lengths, Omni or
Directional transducers, highly reliable acoustic release
mechanism, RS232 interface for test/setup, temperature,
depth and tilt sensors and depth rating to 7,000 metres.
The unit is fully compatible with all Fusion systems, standard
Compatt 5 transponders as well as previous generation LBL
and USBL hardware.
