MicroPap (µPAP) Compact acoustic positioning system

Availability: Rental

µPAP is a small and compact acoustic positioning system for operation from a surface vessel to track ROV’s, tow fish, divers and any other subsea target at ranges to several thousand meters. The system operates in SSBL mode where it measures the distance and direction to subsea transponders and computes a 3D position in local coordinates or in geographical coordinates. µPAP is designed to be a portable system for easy installation on the vessel or other surface unit.
