DGPS measurements provide solid earth tide corrections and the HydroLevel™ buoy GPS receiver incorporates these real-time correctors at the position and time measured by the GPS receiver.

The HydroLevel™ GPS Processor was developed from the successful low-power WatchMan500™ payload processor, specifically designed by AXYS for the marine environment. The processor integrates sensor systems and provides onboard data processing, data logging, telemetry and diagnostic/set-up routines.

Data transmitted from the buoy includes buoy configuration, status data, position, and WatchCircle™ Alarm messages. Data is also stored on the buoy’s internal data logger. AXYS Data Management Software (DMS), can be installed on a PC to automatically receive, decode and display data transmitted from the buoy. Decoded data is auto-archived in both file and database formats for further use.

Set up and communication with the HydroLevel™ buoy takes place either through a waterproof connector on the buoy hull, a Bluetooth wireless connection built into the buoy, or remotely. All of the buoy set-up parameters can be adjusted and monitored using the wireless interface, enabling easy field configuration and testing.
