摘　　要：针对静止轨道卫星,提出一种轨道机动反演模型,在有限离散轨道数据下分析卫星机动时刻,进一步提出态势评估值计算模型,分析机动卫星的相对机动意图。在卫星的机动模型基础上,构建以时间为变量的目标函数,计算得到机动时间。将机动脉冲、接近时间、相对距离归一化处理,构建标准化综合态势指标,对其变化趋势进行拟合,可以定量分析机动态势。以态势指标为约束,设计机动规避策略。仿真结果表明:态势评估值可以有效评估出两颗卫星的运动趋势,优化的单脉冲机动策略可以使态势评估指标趋于减小。For geostationary orbit satellite,a orbital maneuver evaluation model is proposed to analyze the geostationary Earth orbit(GEO)satellite maneuver epoch by utilizing the discrete orbit data.And a index calculation model to analyze space situation assessment(SSA)is proposed.The maneuver objective function is derived in order to calculate the maneuver epoch.A standard SSA index is derived with normalized maneuver velocity,proximity time and relative distance.SSA trend can be quantitatively analyzed by fitting the SSA index.And a single pulse maneuver is designed to evade chasing satellite.Simulation results show the SSA index can effectively evaluate the relative motion of two GEO satellites and SSA index trend is decreasing by the optimized single pulse.
