µPAP

µPAP is a small and compact acoustic positioning system designed for operation from a surface vessel to track ROV’s, tow fish, divers and any other subsea object at several thousand metres range. 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 benefits from the Cymbal acoustic protocol and all functions that are available for the HiPAP products are also available for µPAP. µPAP has full LBL calibration and positioning capabilities and can be used for position box in, calibration and positioning. The system is offering the user a wide range of transponder channels and cNODE transponder models for depths down to 4000 metres. µPAP has built-in motion sensors for compensating the position for vessels' roll and pitch movements.

These models have no need for calibration of roll and pitch alignments but need to calibrate for alignment to the vessels’ gyro compass. The system can be interfaced to the vessel heading sensor and GNSS system. Data output to users are available in established formats. The µPAP 201-MGC contains a motion sensor and a gyro compass. This model has no need for calibration to determine roll, pitch and heading alignments. To meet various demands from the market, µPAP transducer is available in several models with respect to motion sensors and physical size.
