卫星编队飞行相对轨道主被动结合测量方案研究

针对军用编队飞行卫星系统相对轨道测量隐蔽性要求，提出一种具有隐蔽性的主被动结合相对位置及速度测量方案，该方案采取激光测距仪间断工作的方式以减少向外界辐射能量。应用扩展kalman滤波算法，对编队卫星间相对位置及速度进行估计，并且采用计算可观测度方法对系统可观测性进行分析。滤波计算及可观测性分析结果表明该方案满足一定测量精度，验证了该方案的有效性，使该方案具有工程应用价值。

Research on Active/Passive Measurement for Formation Flying with Higher Concealed Ability

For request of higher concealed ability and accuracy which are rose by military satellites,a concealed and active/passive measurement scheme for relative position/velocity is proposed.Un-continuous working method of laser range finder is adopted in the scheme to reduce the radiation of energy.Moreover,relative position/velocity among satellites is estimated by Extended Kalman Filter,and observability analysis is proceeded by obersavability degree calculating.Results of filtering and oberservability analysis indicate that the scheme satisfies certain measurement accuracy,high effectivity and engineering value.
