Abstract :
POS/MV is a position and 3-axis orientation measurement system that implements a tightly coupled Kalman filter based integration of an inertial navigator and differential GPS. This method of measuring position and orientation has advantages over other approaches. In particular when GPS outages occur. The inertial navigator component acts as a “flywheel” through an outage, maintaining data continuity and data accuracy
