摘　　要：针对2颗星编队飞行的情况，描述了卫星近距离运动的Hill方程，利用星上激光仪器设定了星问测量位置矢量进而确定观测方程，设计了最小二乘滤波器来实现相对轨道的确定。结合空间圆编队构形进行了分析和仿真，结果表明最小二乘估计能够有效提高相对位置确定精度，并给出相对速度的高精度估计。Aiming at the situation of two satellites formation flying, the paper describes Hill equations in close formation flying, establishes the observation equations based on the relative measurement distance vector which enacted in the use of laser instrument, designs a least squares filter for the determination of relative orbit. According to a circle formation as an example, the simulation and analytical results show that the least squares estimate is effective in promoting the estimation accuracy of the relative orbit.
