| Abstract: | Through the analysis of GPS satellite clock noise and the research on estimation and prediction of satellite clock error by Kalman filter the differences of accuracy among different style of clock are quantitatively revealed.Meanwhile,combined with satellite clock stability,follow conclusions can be drawn.The stability and precision of GPS Block IIR-M Rb clock is better than those of Block IIR Rb clock and stability and precision of GPS Block IIR Rb clock is better than that of Block IIA Rb clock.Compared w... |
