DWR-G
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.

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.
Today, the DWR-G is a recognised wave measuring buoy and has taken its place in oceanography.
