摘　　要：对空间飞行器轨道进行仿真验证,是轨道方案设计与性能评估的重要途径之一,其可信性在模型验证与确认中具有重要作用。基于轨道仿真序列图像的空间飞行器轨道验证反演方法,通过对不同高度类型的空间飞行器轨道进行可视化建模与仿真,把得到的仿真图像序列与成像系统参数相结合,计算出空间飞行器测角坐标,然后通过空间关系分析,构建关于真平均运动角速度与视平均运动角速度的约束方程,把对空间飞行器轨道运动状态参数的解算,归结为根据轨道仿真图像序列计算空间飞行器测角坐标和根据测角坐标确定观测斜距,解决了利用图像数据进行非合作空间飞行器轨道反演验证过程中轨道初始参数的确定问题。Simulation validating of spacecraft orbit is an important approach of orbit scheme designing and performance evaluating. Its creditability is pivotal in the orbit model validating and affirming. The reversal method of validating of spacecraft orbit took the images of orbit simulation as source date. On the basis of visualization and simulation of all kinds height of spacecraft orbit, this method firstly calculated longitude and latitude by the orbit series image and the imaging system parameter. Through analysis of the vector relation of spacecraft among the space reference frame, an equation restricted by the real average-angle-velocity and the calculated average-angle-velocity was designed, which adopted orbit elements calculating based on the longitude-latitude data proposed from the series image and the object distance estimation. The reversal method of validating of spacecraft orbit develops a resolution of how to calculate spacecraft orbit initialized parameters.
