APOS Acoustic Position Operator Station system software

The HiPAP® and HPR systems are operated from an acoustic positioning operator station (APOS). The operator station is a Windows based PC running dedicated acoustic positioning software.

HiPAP® and HPR can be operated from a single APOS station or through a number of APOS operator stations connected in a network. The APOS software can be integrated with KONGSBERG dynamic positioning systems.

APOS base version

Base software for running all applications including:

  • Sound velocity profile function
  • Ethernet interface for position data
  • Serial line, RS 422 for transceiver interface
  • Serial line, RS 422 for position data

Transponder telemetry for SPT/MPT transponders

  • Set transmit power level
  • Set receive sensitivity
  • Change channel
  • Enable/Disable
  • Transponder release
  • Read battery status
  • Read sensor data, if any

Position and angle alarm

  • APOS software for HiPAP® or HPR 400 providing alarm for transponder position and riser angle alarm

APOS Depth sensor interface

  • APOS software for interfacing a depth sensor for depth compensation of position. Suitable for ROV or Tow fish positioning

HiPAP 501 SSBL function

NOTE: Export license is required. APOS software for HiPAP® SSBL operation including:

  • Transponder positioning
  • Responder positioning
  • Serial interface for gyro and VRU or attitude sensor (maximum 3 units total)
  • SSBL simulator for training

HiPAP 351 SSBL function

NOTE: Export license is required. APOS software for HiPAP® SSBL operation including:

  • Transponder positioning
  • Responder positioning
  • Serial interface for gyro and VRU or attitude sensor (maximum 3 units total)
  • SSBL simulator for training

HPR 400 SSBL function

APOS software for HPR 410 SSBL operation including:

  • Transponder positioning
  • Responder positioning
  • Use of MF or LF transducers
  • Interface for one synchro GYRO
  • Interface for one analogue VRU
  • Interface for one serial GYRO or attitude sensor
  • SSBL simulator for training

A responder controller PCB is required for responder use

LBL function

APOS software for Long Base Line operation using HPR 408/418 or HiPAP®, including:

  • Calibration of transponder array in local grid
  • Positioning of vessel/ROV in LBL array
  • Necessary transponder telemetry
  • LBL simulator for training
  • Geographical position output if transponder locations/origin are entered in geo co-ordinates

This function requires that the system already has the "APOS Base Version" and "HiPAP® SSBL function" Positioning of an ROV in LBL requires an HPR 400S unit. NOTE: Requires export license

HPR 410P SSBL function

APOS software for HPR 410P SSBL operation including:

  • Transponder positioning
  • Responder positioning
  • Use of PMT 301 Transducer w/ internal roll/pitch inclinometers

A responder controller PCB is required for responder use

HiPAP® MULBL function

APOS software for HiPAP® MULBL operation including:

  • Calibration of transponder array in local grid
  • Positioning of vessel in MULBL array
  • Necessary transponder telemetry
  • Setting of fast LBL update rate through the master transponder

This function requires that the system already has both the HiPAP® SSBL and LBL functions

MULBL transponder array data

HPR 406 - Short Base Line (SBL) software

Basic SBL operating software for the SBL range of transducers. Position calculation is based on range measurements between the transponder and different hull mounted transducers with known geometry. Computes a three dimensional transponder position relative the vessel. Including the following standard operational features:

  • Position data output on serial line
  • Up to 56 transponder channels
  • Setting of individual interrogation rates
  • Polar or Cartesian coordinates
  • Self testing modes
  • Tailing track plot on screen
  • Auto saving of all operator settings in case of power failure
  • Transducer offsets (to the reference point onboard) are available on screen to the operator
  • Vessel symbol on screen displayed in real scale
  • Electrical and acoustic error messages on the display
  • Noise spectrum analyze capabilities with printouts
  • Operator selectable filtering on screen
  • Operator selectable scale on screen
  • Operator set sound velocity inputs
  • Ray-bending computation with graphical presentation and error correction for angles and ranges (available when input of sound velocity profile)
  • Vertical angle accuracy improvements, after operator set transponder depth input. Minimizes the effect of acoustic deflection due to thermal layers (when velocity profile is not available)
  • Optional multi operating stations available, working in master/slave configuration(s)
  • Optional GPS interface available for allowing positions to be presented in global coordinates
  • Positioning software based on angle and range measurements
  • Transponder mode. The transponder will reply on an acoustic interrogation pulse
  • Position and angle offsets on transponder installations
  • Optional Responder mode is available. The responder is triggered on a cable, rather than by acoustics. Convenient in noisy subsea environments
  • Optional Beacon (Pinger) mode available, for high position update rate
  • Optional "Pulse Position Telemetry" for reading different sensors in the transponder, such as Inclinometers, depth sensors, etc.
