| Abstract: | A method for performing the high accuracy time calibration of satellite onboard control system with the GPS time information is presented. In this method, the Pulse Per Sceond (PPS) sent by the GPS receiver is served as the reference, while the broadcast time of GPS whole-seconds is received to perform the autonomous time calibration of satellite onboard control system, this allows the time calibration accuracy of satellite onboard control system to be over 0.1 ms and also meet the high accuracy time requirements of satellite. |
