基于STK的卫星轨道机动模型设计与仿真

轨道机动是卫星完成任务常用的手段，在分析卫星星下点轨迹和覆盖区计算方法的基础上，以能量消耗最少为约束条件，对分辨率不符合要求、过境时间不符合要求、卫星在一昼夜内不过境三种情况下的卫星轨道机动问题进行了分析和理论推导，得出相应的卫星轨道机动模型，并采用STK对几种轨道机动方案进行编程设计，通过二维和三维图进行演示，计算结果与STK的数据达到高度一致，全面验证了轨道机动中的各种关键模型，对卫星轨道机动的实际应用有较好的借鉴价值。

Design and Simulation of Satellite Orbital Maneuver Model on STK

Orbital maneuver is a common means to accomplish task for satellite. By Analysing the method of calculating the satellite ground trail and covering area, and on condition that energy consumed is least, the satellite orbital maneaver problems are researched on three conditions, namely:no satisfactory definition; time of passing territory doesn't satisfy the requirement; and not passing territory in one day and night. STK is adopted to design orbital maneuver scenario. The models of satellite orbital maneuver are demonstrated and verified through planar and three-dimensional figures. The result is consistent with data of STK and validates various key models, and will have good value for application in satellite orbital maneuver.
