摘要
随着我国在轨卫星数量增多,多星频繁过境,对任务准备时间提出了新的要求。为了进一步缩短任务切换时间,需要改进标校策略,优化自动标校流程,通过分析统一扩频测控系统的标校数据,研究校相结果的稳定性以及对天线自跟踪性能的影响。拟合出了2套测控设备标校结果与频率之间的关系曲线,提出了集中标校方案。经实际工程验证,该方案能够节省任务中标校的时间,提高自动运行效率。
The increasing number of satellites in orbit and the frequent passing of multiple satellites have a higher requirement for mission preparation time.To shorten the mission switching time ,it is necessary to improve the calibration policy and optimize the auto- matic calibration process.By analyzing the calibration data of unified spread spectrum TT＆C system,the stability of calibration results and the impact on automatic tracking performance of antenna are studied.Then,the correlation curve between the calibration results and frequencies of two sets of TT＆C equipment are fitted.At last,a centralized calibration scheme is proposed.Practical engineering verification shows that the scheme can decrease the calibration time in mission implementation and improve the efficiency of automated operation.
