Scripps chooses HYDRINS for its research vessel Roger Revelle

The Scripps Institution of Oceanography, based in San Diego, California, USA, has chosen IXSEA technology for a key aspect of its marine survey activities.

The Institute has fitted a HYDRINS inertial navigation system (INS) to its research vessel Roger Revelle to provide information about the motion and position of the vessel when gathering multibeam sonar data.

Rick Morton, IXSEA's North American Sales Manager-Geosciences, said "This is repeat business with one of the world's best-known oceanographic organisations. The new HYDRINS is a replacement for an earlier unit and incorporates several subtle performance enhancements, the result of a continuing equipment development program at IXSEA. On this occasion the unit was supplied by our sales agent in California, Ocean Innovations."

Based on Fibre-Optic Gyroscope technology, HYDRINS is a compact, high-performance INS that has been optimised for use in conjunction with multibeam echosounding equipment. Designed to cope effectively with GPS drop-outs and multipath effects, it delivers accurate position, attitude and velocity data in real time.

Alternatively, HYDRINS raw data can be post-processed using IXSEA's purpose-designed DELPH INS software.
