Remote time and frequency transfer experiment based on BeiDou Common View

Last year the zero-baseline common-view test using BeiDou Navigation Satellite system (BDS) is done in BIRMM and the result is better than 5 ns. In this year, we have developed our own GPS/BD common view time and frequency transfer receiver. Using this receiver we carried out two remote common view experiments in BIRM-SIMT link and BIRM-NTSC link, separately. Besides, we took out TWSTFT experiment together when we made the common view experiment to check out our common view result. The experiment and some results are shown in this paper which show that the common view precision using BD is at the same level of GPS but slightly lower than that of GPS.
