Turn your navigation or meteo-buoy into a directional wave buoy with this GPS-based wave motion sensor package.
Shipping lanes and harbour entrances are usually marked by numerous navigation buoys. Especially at these locations seafarers are interested in the wave conditions. Furthermore, networks of marine and meteorological monitoring buoys cover the oceans for weather forecasting and climate change studies. Such networks offer a good opportunity to collect ocean wave data as well. These are just two examples for application of the Datawell DWR-G unit: a directional wave motion sensor package based on GPS.
The DWR-G unit builds on the Datawell principle of measuring waves with a single Global Positioning System (GPS) receiver. No differential GPS receiver is required. The same principle is also exploited in the DWR-G directional Waverider buoys. It offers 3-dimensional motion with centimetre-precision up to wave periods of 100 seconds.
All data are output through one RS-232 port. The DWR-G unit outputs the well-known HXV format of the Waverider buoys which provides raw displacement, full spectra and buoy position. A single cable carrying power and signal lines enters the unit. The unit has a base plate with 4 holes for mounting. Since GPS refers directly to the WGS84 reference frame no special alignment is required.
Datawell is a company which develops oceanographical measuring instruments.
