摘要
为了提高C波段双向卫星时间频率传递(TWSTFT)精度,用载波相位观测值平滑伪距的方法,计算电离层延迟对C波段双向卫星时间频率传递的影响。在临潼站和喀什站观测北斗G3星并进行双向比对。该实验结果表明,实验期间C波段双向卫星时间频率传递中电离层延迟影响的最大值为0.47 ns。
For improving the precision of C-band TWSTFT(two way satellite time and frequency transfer),the ionospheric time-delay effect on C-band TWSTFT is calculated with the method of using the carrier phase data to smooth the pseudo-range.The COMPASS G3 satellite was observed at Lintong station and Kashi station,and the TWSTFT between these two stations was conducted.The results show that the maximal ionospheric time-delay effect on C-band TWSTFT was 0.47 ns during the experiments.
