Rapidly changing motion means that every aspect of positioning must be carefully re-examined and re-evaluated to avoid costly and dangerous positioning errors. The frequent changes in heading, acceleration and deceleration inherent in rockets, missiles, jet planes, race cars and other platforms — up to 100 times per second! — dictate a very high rate of data inputs from both inertial and GNSS sensors to capture the complex trajectory.
