IXBlue Hydrins inertial navigation system
accepted
An inertial navigation system for use in multibeam echo sounder systems. It uses fibre optic gyros and accelorometers to determine heading, attitude and position (via dead reckoning). The unit can accept positional aiding from Global Positioning Systems (GPS) and Doppler Velocity Logs (DVL). There has been more than one generation of the unit, however, the heading accuracy is typically better than 0.02 deg and the roll or pitch accuracy is better than 0.01 deg. The navigation system was first manufactured by IXSea which is now part of IXBlue.
