Description
Sonardyne's COMPuting and Telemetering Transponder (Compatt) Mk4 is a microprocessor controlled subsea transponder used for acoustic navigation and positioning. Available in three frequencies to suit varying requirements of accuracy and range, Compatt is the internationally recognised instrument for subsea construction, survey and field development applications. The latest release of Compatt firmware gives complete flexibility over choice of interrogates and replies channels. By adding 3 extra frequency channels, it is now possible to operate 3 systems in close proximity without mutual interference during navigation*. Also included is the ability to lock the Compatt status so that command corruption will not be able to take a beacon off-line accidentally. Key Features
- Sequential mode operation with 15 individual channel frequencies
- Simultaneous receiver card for high speed positional updates
- Unique addresses allow up to 945 Compatts to be used in close proximity
- Programmable address code and channel channel via RS232
- Conventional Enable and Disable commands for normal transponder
- Remote selection of reply frequency helps overcome interference
- Advanced telemetry can reply to all commands with address, command executed and error-checking
- Direct baseline measurement to better than 15cm between Compatts greatly improves array calibration accuracy
- Temperature and depth measurements allow sea-bed sound velocity evaluation
- Battery check records battery capacity and time since last charge
- Remote power control to reduce output in reverberent conditions or to extend battery life
- Compatt status can be remotely monitored and variables reset
- 4 gain control settings
- Cycle mode permits up to eight preset commands to be executed on receipt of one command
- Compatible with all Sonardyne and HPR300/400 channels
- Auto-disable at 90% of battery pack usage. Acoustic override
- Internal tilt sensor ±45°
