    Hydroid integrates Kongsberg Maritime’s HiPAP system with REMUS AUV

    Vessel & ROV News // January 18, 2011

    Hydroid, a subsidiary of Kongsberg Maritime, the manufacturer of Autonomous Underwater Vehicles (AUVs) has announced that it will offer the integration of Kongsberg Maritime’s High Precision Acoustic Positioning (HiPAP) system into its family of REMUS AUV’s.

    The HiPAP system will provide REMUS users a faster, more accurate way to obtain a vehicle’s exact position and to update the vehicle’s navigation system. 

    The REMUS navigation system currently provides an accurate real-time estimate of its position, velocity, and heading, which permits the vehicle to autonomously self-navigate and to geographically reference and time stamp all data collected during a mission.

    If desired, the onboard navigation system may be aided by acoustic transponders that are located on the seafloor, or, in shallow waters, aiding may be provided by surfacing and obtaining a position update using the Global Positioning System (GPS).

    Kongsberg Maritime’s HiPAP provides an additional means of aiding REMUS’s navigation system by transmitting an independently established location, which is calculated by the HiPAP system on the surface and then sent to the submerged REMUS vehicle over an acoustic communication link.

    “We believe that the integration of technologies offers Hydroid customers a more efficient way of establishing and updating REMUS’ position, when operating outside an acoustic transponder field in deeper waters”, said Christopher von Alt, President and one of the co-founders of Hydroid.

    HiPAP is a family of high precision baseline acoustic position systems, which can provide precise range and bearing to an acoustic transponder on the vehicle. When combined with heading, pitch, roll, yaw and ship position data, the positioning system can support the computation of the vehicle’s subsea position in near real time.

    The HiPAP information is used either to track the vehicle or to update and bind the vehicle’s position if it is accurately time-stamped over the acoustic communication link.

    HiPAP’s unique transducer technology and advanced digital signal processing form an ideal solution for obtaining an AUV’s exact position at any time when it’s in range of the ship.
