GAPS


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