Compatt Mk4 LF (Discontinued)
Description
Key Features
The Computing and Telemetering
Transponder (Compatt) is a
microcomputer controlled subsea
transponder used for acoustic
navigation and positioning.
• Sequential mode operation with
ten individual channel frequencies
The Type 7802 Compatt Mk4 is the
Low Frequency (8 - 16 kHz) version
of Sonardyne’s fourth generation
family of transponders built to
complement the existing range of
Long BaseLine products. The LF
system is suited to long range tasks
such as underwater measurement,
remote control and monitoring,
where ranges of up to 10km can be
achieved in adequate water depth.
• Simultaneous receiver card for high
speed positional updates fitted as
standard
• Unique addresses allow up to 512
Compatts to be used in close
proximity
• Programmable address code and
channel via RS232
• Conventional Enable and Disable
commands for normal transponder
operation
• Advanced telemetry facility replies
to all commands with Compatt
address, confirmation of command
executed and error-checking
• Direct measurement of baselines
between Compatts greatly
improves array calibration
accuracy
• Baseline measurement 60cm
• Temperature and depth
measurements allow sea-bed sound
velocity evaluation
• Battery check records remaining
battery capacity and time since last
charge
• Remote status Monitoring
• Cycle mode permits up to eight
preset commands to be executed
on receipt of one command
• Auto-disable at 90% battery pack
usage.
