【摘要】：面向光学卫星观测平台的视线测量精度需求,研究了一种基于区间分析理论的误差分配方法.基于先进的卫星、转台、相机结构,建立了惯性系下空间相机与目标间的视线矢量测量模型及测量误差模型.根据区间分析理论,给出了误差灵敏度的评价方法.根据星载观测平台的工作空间,得到了各项误差源在三个轴向上的全域最大灵敏度.以全域最大灵敏度为权重系数,建立了星载观测平台视线测量的误差分配模型,通过遗传算法将13项误差源的可行区间松弛致最大.Monte Carlo仿真验证了该误差分配方法的有效性,该方法也同样适用于机载、车载等观测平台的误差分配研究.
[Abstract]:An error allocation method based on interval analysis theory is studied to meet the requirement of line of sight measurement accuracy of optical satellite observation platform. Based on the advanced satellite, turntable and camera structure, the measurement model and measurement error model of the line of sight vector between the space camera and the target under the inertial frame are established. According to the theory of interval analysis, the evaluation method of error sensitivity is given. According to the workspace of the spaceborne observation platform, the global maximum sensitivity of each error source on three axes is obtained. Taking the maximum sensitivity of the whole region as the weight coefficient, the error allocation model for the line-of-sight measurement of the spaceborne observation platform is established. The validity of the error allocation method is verified by the simulation of the maximum relaxation of the feasible range of 13 error sources by genetic algorithm. The method is also applicable to the research of error allocation for airborne and vehicular observation platforms.
