Datawell Directional Waverider DWR-G7



Measure waves with GPS

Datawell     |     DWR-G7

The DWR-G wave buoy measures waves with help of the Global Positioning System (GPS) only. It features a patented algorithm and custom-made GPS receiver. With a single stand-alone GPS receiver it can measure directional waves, up to 100 s periods, without any calibration ever, and even in the middle of the ocean.

Already with its introduction in 2002 the new GPS measurement principle was tested against the standard in the field of wave measurement: the Datawell Directional Waverider (MkII). For a copy of these publications please visit our website or contact Sales. By now the GPS buoy is well-established and has taken its own place in the oceanographic market.
