Getting Their Feet Wet


A joint Applanix / Fugro solution for improved subsea positioning.

With global offshore oilfield exploration's continued move towards deepwater development, the technologies that allow ROVs (Remotely Operated Vehicles) and AUVs (Autonomous Underwater Vehicles) to efficiently carry out precision surveys, and subsea maintenance tasks, are becoming significantly more important.

POS MV is a user-friendly, turnkey system designed and built to provide accurate position, heading, attitude, heave, and velocity data of your marine vessel and remote sensing equipment. With over one thousand systems deployed worldwide, POS MV is field-tested and proven in all conditions. POS MV blends GNSS data with angular rate and acceleration data from an IMU, and heading from GPS Azimuth Measurement System (GAMS) to produce a robust and accurate full six degrees-of-freedom position and orientation solution.

POS MV comes in 5 models:

  • POS MV SurfMaster I
  • POS MV SurfMaster
  • POS MV WaveMaster II
  • POS MV OceanMaster
  • POS MV Elite

All POS MV models are designed for use with multibeam sonar systems, enabling adherence to IHO (International Hydrographic Survey) standards on sonar swath widths of greater than ± 75 degrees under all dynamic conditions. At the entry-level is the POS MV SurfMaster, which delivers robust georeferencing for small platforms, both manned and unmanned. Fully supported by Applanix’ industry leading post processing software, POSPac MMS, SurfMaster delivers roll and pitch accuracy to 0.03 degrees. Wavemaster II and OceanMaster are designed for increasingly difficult conditions and performance requirements. The POS MV Elite is for users seeking the very highest level of performance available to the industry.

POS MV was used aboard HMS Enterprise for an ocean floor scan under the Red Sea. A Red Sea "Grand Canyon" was discovered. To see the article, click here.

•    Exceptional performance under all dynamic conditions
•    Provides almost instantaneous reacquisition of RTK following GPS signal loss
•    Very low noise L1 and L2 carrier phase measurements
•    Maintains heading accuracy in a high multipath environment and in areas of poor GPS availability
•    Automatic initialization upon power-up, following a one-time calibration
•    Superior low-elevation tracking performance regardless of latitude
•    Continuous sensor monitoring to ensure optimum performance

Applanix' POS™ technology was originally developed and rigorously tested as part of an extensive military project. This proven technology was enhanced, customised and packaged to yield an off-the-shelf commercial product, uniquely suited to the requirements of precision marine motion sensing, hydrographic surveying and charting.

Current users include many of the world's largest marine contractors and navies, which rely on POS MV's accuracy and robustness for their precise marine survey requirements.

TrueHeave Software
Using new heave processing algorithms TrueHeave now enables heave data to meet and exceed the highest marine industry standards.

POS MV systems equipped with TrueHeave technology have sufficient computational speed to generate a secondary estimate of heave shortly after the initial sonar acquisition event. Delayed time heave output not only removes many of the compromises that must be made in real-time, but also provides near real-time QC of heave performance.

Cost effective solution
TrueHeave significantly reduces filter settling time when compared to traditional heave filters, which can almost completely eliminate the need for line run-ins. This means a saving of several minutes per survey line, which can translate into a saving of hours or even days worth of labor and vessel costs.
