Ship Detection System

HELZEL Messtechnik GmbH is the German TÜV certified manufacturer of the well known Remote Ocean Sensing System WERA. The shore-based WERA provides reliable data of ocean surface currents and significant wave height and direction over long distances (> 200 km) with outstanding spatial and temporal resolution for VTS, SAR and environmental protection applications.

The robust shore based system delivers reliable data even under extreme weather and very dynamic ocean current conditions. Numerous live comparisons of the WERA data with other measurement techniques prove the high quality of the near real-time measurements of the system. Time series comparison of the surface currents (WERA data in black) and sub-surface currents measured with an ADCP current meter during the experiment at the west coast of Florida.
