POS MV maintains positioning and orientation accuracy under the most demanding conditions regardless of vessel dynamics. POS MV provides high update rate (up to 200 Hz) georeferencing and motion compensation for vessel mounted remote sensing systems.
THE POS MV ADVANTAGE
• High quality, state of the art Inertial Measurement Units (IMUs) developed by the
world’s leading supplier of inertial technology
• IMUs with high quality accelerometers and gyros integrated into a strap down
navigation solution proven to produce the best results for resolving individual multibeam
pointing angles
• Robust heading aiding from GPS Azimuth Measurement Subsystem (GAMS)
• Proprietary tightly coupled Inertially Aided GPS technology providing robust
positioning with industry leading immunity to GPS outages and almost instantaneous
reacquisition of RTK following a GPS outage
• Industry leading real time Heave estimation
• TrueHeave™ implemented for maximum immunity to filter transients and phase
lag error
• The only positioning and orientation system with full raw data logging capabilities
suitable for use in the Applanix POSPac post processing package.
• The only Inertially Aided Post Processed Kinematic (IAPPK) Solution in the Marine
Hydrographic industry providing the most accurate positioning and orientation
results possible
• Proven reliability with over 400 systems in service, the Applanix POS MV is the
proven industry standard for Marine Hydrographic Surveying
