风云二号卫星地面控制系统自适应同步控制方法

Adaptive and synchronous control method for ground control system of FY-2 satellite

针对风云二号07星测控实施过程中部分姿章联控参数未能正常执行的系统间时序控制不同步问题,研究提出一种地面控制系统自适应同步控制方法,分析卫星历史数据得到有效接收时间区间,取所有有效接收时间区间的交集得到最终有效接收时间区间。经验证,方法可有效解决系统间时序不同步的问题,精度高,控制效果好。

To solve the problem of the out of sequence control sync between systems caused by the joint control of attitude and nutation parameters failing to execute in the TT&C process of FY-207 satellite,the adaptive and synchronous control method for ground control system is proposed.We analyze the historical data to achieve the effectively receiving time intervals and take the intersection as the final result.It is proved that this method of high precision and good control effect can effectively solve the problem of the out of sequence control sync between systems,which is meaningful for the synchronous control of spin-stabilized satellites.
