3 Export licensing restricts operation to a maximum of
18,288 meters and 514 meters per second.
4 If raw IMU measurements are logged (200 Hz), the
max rate position, velocity, attitude logs can be
requested is 50 Hz.
5 These values were computed using forced GPS
outages in data collected under good GPS availability
conditions in a land vehicle. The errors are calculated
as the difference between the full availability trajectory
and the the trajectory with forced GPS outages.
