POS LV is a compact, fully integrated, turnkey position and
orientation system, utilizing integrated inertial technology
to generate stable, reliable and repeatable positioning solutions
for land-based vehicle applications.
Designed to operate under the most difficult GPS conditions
found in urban and suburban environments, POS LV enables accurate
positioning for road geometry, pavement inspection, GIS database
and asset management, road surveying, and vehicle dynamics.

The increased demand for accurate absolute positioning has meant the more traditional georeferencing methodology, of using linear distance traveled to provide relative location data, is now no longer acceptable for many applications.
The POS LV system generates precise, robust positioning and orientation information for mobile data acquisition systems. The system combines all the advantages of GPS with those of inertial technology, to provide continuous and accurate data. By utilizing the POS LV system, data capture can be undertaken quickly and efficiently.

- IMU: Inertial Measurement Unit generates a true representation
of vehicle motion in all three axes, producing continuous,
accurate position and orientation information
- PCS: POS Computer System enables raw GPS data from as
few as one satellite to be processed directly into the system,
to compute accurate positional information in areas of intermittent,
or no GPS reception
- DMI: Distance Measurement Indicator computes wheel rotation
information to aid vehicle positioning
- GPS Receivers: Embedded GPS receivers provide heading
aiding to supplement the inertial data
- GPS Antennas: Two GPS antennas generate raw observables
