摘要
采用空间坐标系和矢量的定义,对空间的非线性轨迹进行逐步线性化归纳为点的数学描述,目的是求解地球上任一时刻、任一地点的空间坐标(x,y,z,t),从而知道其所在地球上的位置;同时又进一步用最小二乘法对其位置数据进行优化,补偿一定误差,提高其位置的精确度.
To solve the space coordinate of any point at any time and determine the position on the earth, the definition of space coordinate system and vector are adopted. The space nonlinear contrail is lined by step and is described in mathematical ways. At the same time, the position data is optimized by Least-squares method and its error is reduced, the position precision of which is improved.
