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...
This paper describes a time transfer system that allows timing laboratories, including metrology institutes and other designated institutions, to compare the local realization of Coordinated Universal Time (UTC) with each other. The time transfer system could calculate the difference between the local time and GPS time, and the difference between the local time and BDS time. It stores the measurement...
With the development of BeiDou(BD) Navigation Satellite system, BD can be another choice for remote precise time and frequency transfer. A strict common view test using BD Navigation Satellite System is carried out in this paper. Since there are GEO, IGSO and MEO satellites in BD Navigation Satellite system, common view based on GEO, IGSO and MEO are discussed in this paper separately. Finally, we...
This paper gives a test method of BeiDou timing receiver delay. A BeiDou System simulator and a time interval counter were used in the experiments. During the process, the most important step is to calibrate the delay of the simulator. The uncertainty of this method is analyzed to be less than 1.5ns. Using this method, some typical Chinese commercial timing receivers were tested, and the results are...
