HIPAP® 351P

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 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 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 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 supports variable data speed for acoustic communication to adapt to various acoustic conditions.Sensor data from the transponders are transferred together with navigation pulses.

TECHNICAL SPECIFICATIONSGeneral 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. Range detection accuracy with use of Cymbal is 0.01 m.Degree of protection IP 68

Environmental conditionsStorage temperature -40 to 70°CStorage humidity 95% relative (non condensing)Max. operating temperature in air +35°C*Max. operating temperature in water +35°C*Due to the risk of overheating the transducer electronics when the unit is on deck, internal temperature switch will switch off the power if the internal temperature exceeds 60°C.

NoteIt is very important to use transponders with strong enough output source level to obtain highest S/N ration and thereby also the best SSBL accuracy. All HiPAP 351P models include attituce sensors with different accuracies. HiPAP 351P includes MRU-H, HiPAP 351P-5 includes MRU-5 , and HiPAP 351P-I and HiPAP 351P-MGC includes an IMU that provides the 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.
