1 Typical values. Performance specifications subject<br />
to GPS system characteristics, US DOD operational<br />
degradation, ionospheric and tropospheric conditions,<br />
satellite geometry, baseline length, multipath effects<br />
and the presence of intentional or unintentional<br />
interference sources.<br />
2 Expected accuracy after static convergence.<br />
3 Export licensing restricts operation to a maximum of<br />
18,288 meters and 514 meters per second.<br />
4 If raw IMU measurements are logged (200 Hz), the<br />
max rate position, velocity, attitude logs can be<br />
requested is 50 Hz.<br />
5 These values were computed using forced GPS<br />
outages in data collected under good GPS availability<br />
conditions in a land vehicle. The errors are calculated<br />
as the difference between the full availability trajectory<br />
and the the trajectory with forced GPS outages.<br />
