* Position accuracy [°] can be calculated by √(X2 + Y2). Values are based on use of Cymbal mode, free line of sight from transducer to transponder, no influence from ray bending, Signal to Noise ratio as specified in water in the 250 Hz receiver band, no error from heading/roll/pitch sensors. Operating ranges are typical and conservative, and are assumed by using KONGSBERG transponders with sufficient source level.

All HiPAP 351P models includes attitude sensors with different accuracies as follows :

  • HiPAP 351P: Includes MRU-H
  • HiPAP 351P-5: Includes MRU-5
  • HiPAP 351P-MGC: Includes MGC IMU
  • HiPAP 351P-I: Includes HG9900 IMU

NOTE

It is very important to use transponders with strong enough output source level to obtain the highest S/N ratio and thereby also the best SSBL accuracy.

ACOUSTIC POSITIONING OPERATING STATION FOR HIPAP AND HPR

The HiPAP and the HPR systems are operated from the acoustic positioning operating station (APOS) – a computer with a Windows based operating software. The systems can be operated from one single APOS station or from a wide number of APOS operator stations connected to a network. The APOS software can be integrated with Kongsberg Maritime Dynamic Positioning systems.

KEY TECHNICAL INFORMATION

THE APCXX COMPUTER

The Acoustic Processing Computer (APCxx) is a powerful industrialized standard computer available in 19 inch rack, desktop or console versions.

APOS SYSTEM SOFTWARE

The APCxx computer has customized software specially designed to meet the subsea survey and DP operator demanding requirements. This software is programmed on a standard Windows operating platform.

KEYBOARD

A standard PC keyboard with numerical keys and a trackball, controls the operation.

COLOUR MONITOR

The screen is divided into 3 windows in which the operator can select several different views. Typical views are: graphical position plot, numerical data, inclination, roll, pitch and heading.

A normal display configuration is illustrated to the left.

One system may have one or several operator stations, which communicates on an Ethernet. One of the operator stations will be the Master. This is selected by the operator(s).
