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 HiPAP351P models includes 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 Operating range and the SSBL accuracy specifications are based on; free line of sight from transducer to transponder, no influence from ray-bending, Signal to Noise (S/N) ratio in water in the 250 Hz receiver band, and no error from heading and roll/pitch sensors. The angular figures are errors in both axis, elevation and orthogonal.

Two different product lines

We presently offer two different lines of Acoustic underwater positioning and navigation systems:

  • HiPAP family - High precision acoustic positioning system
  • µPAP - Small and portable acoustic positioning system

Key HiPAP features

  • Unique spherical transducer design with up to 241 individual elements
  • Extraneous noise suppression techniques
  • Extremely narrow, ±5 degree listening beams
  • Extreme tracking range capabilities
  • True Multi-User LBL function
  • Comprehensive transponder range to support positioning operations
  • Reference output to dynamic positioning system
