中文摘要：
双向卫星时间比对是一种高精度的远程时间比对手段，其比对经常不是连续进行的。为分析非连续双向卫星时间比对的水平，使用中国科学院国家授时中心的C波段双向卫星时间比对网的数据进行试验。采用的方法是对非连续双向卫星时间比对的结果进行内插，将内插结果与连续双向卫星时间比对的结果进行比较。结果表明本文试验条件下观测间隔时间在2.5 d以内时，非连续与连续观测结果之差的RMS值小于1 ns；观测间隔时间为0.5 d时，非连续与连续观测结果之差的RMS值小于0.5 ns。
英文摘要：
The two-way satellite time and frequency transfer(TWSTFT) is a kind of remote time comparison method with high precision. Generally, the comparison is not carried out continuously. The data from C-band TWSTFT Network of the national time service center(NTSC) was used for analyzing the level of non-continuous TWSTFT. The raw data of non-continuous TWSTFT was dealt with linear interpolation method and the result was compared with the continuous TWSTFT. The comparison shows that the RMS of the difference between non-continuous and continuous TWSTFT is less than 1 ns when the interval time is less than 2.5 d, and the RMS is less than 0.5 ns when the interval time is 0.5 d.
