Deepwater Acoustic Positioning System

To achieve the accuracy, the HiPAP system utilize unique signal processing techniques. This technique enables narrow transmitter and receiver beams to be generated in all directions within the lower half of the transducer. The HiPAP 602 large diameter multi element planar array combined with electronic beamforming provides high accuracy and long range capabilities well suited for deep water operation.

HiPAP 602 is ideally suited for deep water seabed mining and is fully compatible with the latest HAIN Subsea 7000 inertial navigation system which allows for fast calibration of sparse LBL arrays with the ROV box-in technique.  The new HAIN user interface runs on the HiPAP system.

The increased angular accuracy offered by HiPAP 602 saves operational cost as it can extend the range that SSBL can be used for construction survey operations prior to switching to LBL depending on project specifications.  AUV surveys operating in 6000m water depths will also benefit from increased position accuracy. 

The system is fully compatible with the entire range of medium frequency cNODE transponders and modems, with depth ratings available from 100m to 7000m. 

The robust high speed modem capabilities allow for 3rd party control and data transfer to and from subsea sensors, AUVs and Hybrid ROVs.  A number of link protocols are available to efficiently package and transparently transit the data. 

For long range tow-fish tracking the transducer can be fitted with a 30° tilt adapter for long range tow fish tracking. The HiPAP 502 shares its modular construction principles with the new HiPAP 602 acoustic underwater positioning and navigation system, allowing the HiPAP 602 to be easily converted to a HiPAP 502 by swapping transducers.
