Gaps M7
Pre-calibrated USBL positioning system
Gaps M7 is a high performance Ultra Short Baseline positioning and communication system for locating and communicating subsea assets. It combines an USBL antenna and a fiber-optic inertial navigation system (INS) in the same housing. USBL calibration on the field is not required anymore.Its unique 3D acoustic array enables tracking and communication from the deep sea to extremely shallow water, and even at angles above horizontal.
Description
Gaps M7 is a high performance Ultra Short Baseline positioning and communication system for locating and communicating subsea assets. It combines an USBL antenna and a fiber-optic inertial navigation system (INS) in the same housing. USBL calibration on the field is not required anymore. Advanced acoustic techniques including wideband signals ensure maximum performance in most difficult conditions. Its unique 3D acoustic array enables tracking and communication from the deep sea to extremely shallow water, and even at angles above horizontal.
