- Abstract
For analyzing the effect of GEO(geostationary orbit satellite-GEO) Satellite Motion on Signal Performance in TWSTFT(Two-Way Satellite Time Frequency Transfer), the observation data of TWSTFT and GPS PPP(GPS Precise Point Positioning) which have the similar accuracy between the NTSC (National Time Service Center) and the PTB (Physikalisch-Technishche Bundesanstalt(Germary)) from November 2013 to November 2014 are analyzed. The results show that the motion of GEO satellite has a definite effect on the signal performance, when the satellite used for TWSTFT system starts inclination, the effective observing time is shortened , and the amount of effective observation data is reduced and the data of time difference shows worse agreement with that of GPS PPP, meanwhile, the carrier to noise ratio (C/No) and the DRMS of time difference of received signal are degraded and there is a negative correlation between C/No with DRMS. The results may be used for the research and analysis of the effect of GEO satellite motion on the measurement accuracy of TWSTFT.
