Abstract

Aimed at the requirements of satellite control system, according to the principle of time calibration, the differences between batch and recursive time calibration methods are compared, and the different time calibration methods are analyzed and compared from two aspects of calculation amount and calibration accuracy. The performance evaluation criteria and quantitative processing method are established, and the influence of sampling period and time slice on the time calibration performance is studied. The simulation model is established, and the results prove that the interpolation method is suitable for the time calibration of the satellite control system, and the piecewise linear interpolation method has the best performance.
