  • Precision of satellite clock is one of the most important factors in GPS precise positioning,with widely applications of IGS precise ephemeris,which becomes a more and more attractive research orientation.Spectral analysis method is applied to analyze the precision of IGS precise ephemeris clock.The conclusions show that different satellite clocks have different precisions,and some of them have great magnitudes than the so-called precision.
