SUBLOCUS


 
General 
Product Name:SUBLOCUS
Product Description:Sublocus DVL is an underwater acoustic and inertial navigation system that provides accurate position, velocity and orientation at depths of up to 3000 metres. It features a doppler velocity log, high accuracy north seeking fibre optic gyroscopes, accelerometers, an internal GPS receiver and a pressure depth sensor. It accepts external aiding from speed logs, propeller speeds, USBLs, SBLs and LBLs.
Year of introduction:

More information 
Distinguishable features:Sublocus features very high performance inertial sensors combined with Advanced Navigation's revolutionary fusion algorithms. This allows a highly accurate position, velocity, roll, pitch and heading. The fully integrated system, with both a pressure depth sensor and a 6000 metre depth rated GPS receiver provides a pre diving starting position. Sublocus has support for a wide range of peripheral inputs including speed logs, propeller speeds, DVLs, USBLs, SBLs and LBLs.
