In the project Helzel Messtechnik GmbH is responsible for the supply, installation and service of 2 over the horizon radars. Helzel Messtechnik cooperates with the Institute of Oceanography of the University of Hamburg.

The WERA system (WavE RAdar) is a remote sensing system based on short radio wave over the horizon radar technology, operating with very low power. The system output are ocean surface current and wave height maps over a distance of more than 100 km with a spatial resolution of down to 300 m and a time resolution of less than 5 minutes.
