GLOBAL TIMING SYSTEMS OF NANOSECOND ACCURACY USING SATELLITE references.

Abstract

The application of artificial satellites in providing radio reference signals for the synchronization and calibration of local clock and timing systems has been studied. Space technologies in the specific areas of geodesy and navigation are applied with digital signaling techniques and atomic time and frequency standards. The result of the study predicts that a useful operational service can be provided on a global basis with a low-altitude polar satellite having an onboard atomic clock to most effectively satisfy user requirements at various levels of system accuracy. For fixed site users, system accuracies as good as 100 nanoseconds (rms) are realistic with sophisticated equipment and data processing. (Author)
