EchoTrace Pinger - Navigation pinger beacon Device specification |
KEY FEATURES
- No integration required - simply attach it mechanically to the object being positioned
- Maximum ease of maintenance
- Automatic activation in water
- Minimum dimensions and weight
DESCRIPTION
The EchoTrace Pinger navigation pinger beacon of the EchoTrace system is placed on the object being positioned: an ROV, AUV, diver, or other underwater object. It emits a periodic navigation signal received by four floating EchoTrace GIB navigation buoys. The signal is used to determine the geographic position of the pinger. Navigation is combined with telemetry transmission from the pinger, allowing its depth, water temperature, and battery supply voltage to be determined. The pinger requires no interface with the object being positioned; simply attach it to the object.
