can be tilted to utilize the 160° cone operating area in the sector of the required area. There will be no need for extra calibration, or mechanical fine adjustments, as the internal Motion Reference Unit will automatically compensate for the tilt.

A built-in North seeking heading sensor is also available. This is based on an inertial measurement unit including Ring Laser Gyros. This makes heading calibration of the transducer unnecessary which saves time during mobilization/start-up.The HiPAP® 351P series are also

capable of using the new Cymbal wideband signal system available with the cNODE® transponders. The Cymbal wideband signals give higher accuracies, both for range measurements as well as angle measurements. Cymbal adds another 50 channels in addition to the 56 tone channels available. Telemetry speed when using wideband can be up to 8 kbit/sec, depending on acoustic conditions. Senor data from the transponders are transferred together with navigation pulses.

HiPAP® 351P series are the portable models of the HiPAP® systems. With its unique and compact transducer containing receiver and transmitter electronics along with a variety of high quality motion sensors it will bring highest underwater positioning data into the services for “vessels of opportunity”. The HiPAP® 351P series are the only systems available offering automatic beam steering from portable transducers. The transducers are designed to be mounted on a shaft for installation over-the-side or through a moon-pool of a vessel. The transducer

NOTE:It is very important to use transponders with strong enough output source level to obtain highest S/N ratio and thereby also the best SSBL accuracy. All HiPAP 351P models include attitude sensors with different accuracies. HiPAP 351P includes MRU-H, HiPAP 351P-5 includes MRU-5 and HiPAP 351P-I includes an IMU and provides also heading relative north.

1) The SSBL accuracy specifications are based on: free line of sight from transducer to transponder, no influence from ray-bending, 20 dB Signal to Noise ratio and no error from heading and roll/pitch sensors.

General informationOperating range:...................................................1 - 4000 mPosition accuracy in % of range1):................................0,3 %Using cNODE transponders in Cymbal mode can increase accuracy up to 30 % in noisy conditions.
