Description

The μPAP Precision Acoustic Positioning system operates in SSBL mode (LBL is also possible) where it measures the distance and direction to subsea transponders and computes a 3D position in local coordinates or in geographical coordinates. It offers high accuracy but is smaller, more compact and easier to install on a vessel or other surface unit than larger acoustic positioning systems. The size, weight and ease of installation makes μPAP a more flexible solution ideal for a diverse range of applications including, Aquaculture, Seabed Survey, Seabed Cleaning, Marine Research, Diving Operations, Underwater Construction, ROV Operations, Shallow Water Seismic, Shallow Water Inspection, Ocean Renewable Energy and Salt to Fresh Water Production.
