Description
The Computing and Telemetering Transponder (Compatt) is a microcomputer controlled subsea transponder used for acoustic navigation and positioning. 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. Key Features
- Sequential mode operation with ten individual channel frequencies
- 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.
