空间环境参数预报数据在轨控策略中的融合应用

Fusion Application of Prediction Data for Space Environmental Parameters in Orbit Control Strategy

轨迹网保持是在轨卫星生命周期管理中一项长期工作,空间环境变化会对轨道衰减情况产生影响。通过对某型卫星轨道数据和空间环境参数预报数据进行比较分析,利用求解经验公式的方法得出了轨道受空间环境影响变化的规律,使用控后时间点的空间环境预报数据为轨迹网保持策略提供了有效的方法依据,验证了空间环境预报数据与实测数据的相关性,并在一定程度上解决了空间环境对轨控效果的影响。

Track net of sub-satellite point maintenance is a long-term task in lifecycle management for on-orbit satellites.Orbital attenuation will be affected by changes of space environment.Orbital data and prediction data for space environmental parameters of a satellite was analyzed.The rule of the changes of orbits affected by space environment was obtained by the method of solving empirical formula.An effective method based on the prediction data for space environmental of trajectory network maintenance strategy was provided.The correlation between prediction data for space environmental and measured data is verified.To a certain extent,the influence of space environment on orbit control effect has been solved.
