摘要：
A recent clock synchronization experiment between the National Physical Laboratory, New Delhi and the Space Applications Centre, Ahmedabad via geostationary satellite symphonie-II, stationed at 49 degree E longitude, is reported in this paper. As only one satellite transponder was available for this experiment, the two-way transmission of the clock pulses was carried out by switching the transmit-receive roles at the two stations at 5 minute intervals to achieve a nearly simultaneous two-way transmission. Taking into account all the additional delays, the results demonstrated a clock synchronization accuracy of better than 0. 5 mu s. A crystal-based portable clock flown aboard an aircraft confirmed this clock synchronization to within a microsecond.
