1
Time accuracy does not include biases due to RF or antenna delay.
2
Measurement precision should be compared with measurements using the same correlator spacing.
3
Under good CN0 conditions, e.g. 44 dBHz.
4
Export licensing restricts operation to a maximum of 515 meters per second, message output impacted above 500 m/s.
