Kongsberg HiPAP: High Precision Acoustic Positioning System

Availability: Rental, Sale

The Kongsberg HiPAP family consists of the world?s most successful underwater positioning systems. It was first developed with a focus on the Super Short Base Line (SSBL) principle as this was a market requirement of trying to avoid the Long Base Line (LBL) principle in deep water and in accurate seabed survey applications.


Smaller, lighter and less temperature sensitive transceiver unit built within a stainless steel cabinet.

New Low Power Transceiver (LPT) boards with better filtering and signal processing providing an additional 5-6 dB sensitivity.

The improved sensitivity gives better range and angle accuracy compared to previous generation HiPAPs.

The improved sensitivity allows for less source level in the transponder which leads to longer transponder battery endurance.
