摘要:

介绍了一种利用GPS时间信息进行控制系统高精度校时的方法。该方法以GPS接收机发送的秒脉冲为基准, 同时接收GPS整秒广播时间完成控制系统自主校时, 可使控制系统的校时精度优于0.1 ms, 满足卫星对高精度时间的要求。

Usage of high accuracy GPS time calibration in satellite onboard control system
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.
