Abstract
The capability of one-way time service as an important index of satellite navigation system reflects the ability that a satellite navigation system broadcasts the system time to the clients. In this paper, the performance evaluation method of BD one-way time service is designed standing in the clients' position. The UTC(NTSC)-BDT result via Space signal reception method is obtained in NTSC, the performance of BDT is evaluated reference to UTC (NTSC). The results of BD CV is chose as the reference to evaluate the precision of BD one-way time service. Calculating the root mean square error of residual, The uncertainty of one-way time service is 3.01 ns, the result shows that the precision of BD one-way time service have higher level.
