Coordinating GPS Calibrations Among NIST, NRL, USNO, PTB, and OP
註釋Reviewing calibration results over the history since early 1980's among several labs shows very mixed results. The best stabilities of GPS receivers, as given by calibrations, are of the order of a few nanoseconds or better over a year, though many results are quite a bit worse. Absolute calibrations show similar potential, though there are problems. We conclude that more calibrations and standard methods are needed.
