Abstract: 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.
Key words: COMPASS; TWSTFT(two way satellite time and frequency transfer); ionospheric time delay
