doi:10.12060/j.issn.1000-7202.2014.02.15

Abstract

Abstract: By introducing and analyzing the principle about Global positioning system(GPS) time measured ,time error measured and time error eliminated by difference method, the idea which lessens time error and improves time precision is proposed by applying to two GPS receivers in TT&C station. Based on the above idea, the extended first-order difference model is put forward. By using this method, accurate GPS time for TT&C system can be calculated and the time difference of any two TT&C subsystems in station can be synchronized.

Key words: GPS, Time measurement, Differential positioning
