Directional Waverider DWR-G
Measuring waves with GPS
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.

Compact Air Temperature (CAT4)
The CAT4 is a meteorological air temperature sensor integrated in the HF-antenna of the Directional Waverider. It consists of four individual sensors that have different radiative properties and will therefore measure different temperatures. The actual air temperature is derived from these different temperatures. External influences that might affect the measurements, such as evaporative cooling, are detected for validation.
