Attention:
The Motion Sensors (Hydrins 1 and Hydrins 2) are operated by ship's command only.
Summary
HYDRINS is a high-performance inertial navigation system (INS) optimized for hydrographic survey using multibeam echosounders. HYDRINS comprises a single compact unit and delivers highly accurate real-time position, heading, attitude and speed data.
