Description
The Computing and Telemeter Transponder (Compatt) is a microcomputer controlled subsea transponder used for acoustic navigation and positioning. The Medium Frequency (MF, 18-36 kHz) system is suited to a wide range of tasks such as underwater measurement, remote control and monitoring. The Type 7806 Mk4 Compatt is one of the Medium Frequency versions of Sonardyne’s fourth generation family of transponders built to complement the existing range of Long Baseline products. The Type 7806 has a Semi- Directional transducer directing a high source level upwards to overcome high noise levels on surface vessels, especially vessels using thrusters for Dynamic Positioning. The transducer maintains a good source level and sensitivity in the horizontal direction to ensure reliable inter-Compatt ranging for array calibration. The Type 7806 is a direct replacement for the earlier Type 7805 Compatt, but has improved acoustic performance across the whole MF frequency band. Key Features
- Sequential mode operation with 15 individual channel frequencies
- 12 channel receiver for high speed positional updates
- Allows up to 945 individually addressable Compatt to be used in close proximity
- HPR option allows Compatt to be used with Simrad HPR systems
- Programmable address code
- Conventional Enable and Disable commands for normal transponder operation
- Advanced telemetry facility replies to all commands with Compatt address, command executed and error-checking
- Direct measurement of baselines between Compatt improves array calibration accuracy
- Baseline measurement to15 cm
- Measurement of temp. and depth permits accurate evaluation of sea- bed sound velocity
- Battery checks and time/date facility record remaining battery capacity and time since last charge
- Cycle mode permits up to eight preset commands to be executed on receipt of one command
- Auto-disable at 90% of battery packs usage
