Trimble Applanix is a leading developer of high-accuracy positioning, orientation and navigation systems for marine and maritime vessels and platforms. Based on state-of-the-art GNSS-aided inertial technology and sensor fusion, our solutions are uniquely suited to demanding motion sensing and surveying applications in highly challenging waters.
Advanced positioning for hydrographic surveys
Hydrographic surveying, or the accurate measurement and mapping of features and structures such as coastlines, harbors and the seafloor, is critical for supporting a wide range of activities including construction, environmental management, oil and gas, and safe maritime navigation.
Conducting these surveys with sufficient detail and accuracy can be challenging under demanding conditions such as harsh sea states and GNSS outages. Our GNSS-aided inertial positioning technology allows precision georeferencing of survey data, enabling the creation of highly accurate maps. Our products are designed to seamlessly integrate with multibeam sonar systems, and can be installed on dedicated survey vessels as well as vessels of opportunity.

Applanix POS MV
Position and orientation solution for marine motion sensing & hydrographic survey
Applanix POS MV is a full six degree-of-freedom turnkey solution providing high-accuracy position, heading, attitude, heave, and velocity data for marine survey vessels and remote sensing equipment. Blending GNSS data, angular rate and acceleration data from an IMU, and heading from a GPS Azimuth Measurement System (GAMS), it offers the most robust outputs possible under all conditions, including high multipath and GNSS dropouts.The industry-leading solution is designed to be faster, easily and less costly to deploy, offering increased productivity and streamlined workflows. It provides a wide range of features and benefits that elevate performance for any marine survey operation.
Full GNSS support – both GPS and GLONASS observables are utilized to compute the most robust solution possible, and the system provides excellent carrier phase tracking capabilities even in high multipath environments
High-quality inertial sensing – in addition to GNSS data, POS MV also uses accurate inertial data to ensure continuity of position and heading even under GNSS-compromised conditions such as under bridges and in mountainous terrain. Short-term loss of GNSS does not significantly degrade roll, pitch or heading output.
Powerful post-processing capabilities – raw GNSS and inertial observables can be logged for use in Applanix’ POSPac MMS post-processing software, providing improved accuracy and reliability even under the most challenging ocean conditions.
Fugro Marinestar compatibility – POS MV provides support for Marinestar™ GPS and GNSS services, available via subscription from Fugro. These services provide a range of benefits including real-time data, accuracy to sub-decimeter level, and no geographical limitations.
Multiple solutions to suit any survey requirements
POS MV is available in four different models to suit a wide range of accuracy and performance requirements. All models are optimized for use with multibeam sonar systems, enabling adherence to IHO standards on sonar swath widths of greater than ± 75 degrees under all dynamic conditions.
