Abstract
Two-way satellite time and frequency transfer (TWSTFT) is applied in BeiDou Navigation Satellite System for time synchronization of the ground stations. In fact, the geostationary (GEO) satellites have periodic motions around their planned orbits instead of being stationary to the ground stations, which results in periodic fluctuations of Sagnac correction and signal path geometry correction in TWSTFT. Precise TWSTFT is relaying on the non-reciprocity corrections. An analysis method with broadcast ephemeris of GEO satellite for Sagnac correction and signal path geometry correction is introduced in this paper. With this method, TWSTFT experiment result using BeiDou GEO satellite at 140°E of three links between Beijing and three different sites is analyzed and the periodic fluctuation of Sagnac correction and signal path geometry correction are presented in detail. The fluctuation range of Sagnac correction is from 0.04 to 0.16 ns and that of signal path geometry correction is from 0.01 to 0.53 ns for the three links, which shows that Sagnac correction and signal path geometry correction can not be ignored in time transfer requiring sub-nanosecond precision generally for the three links.
