摘　　要：从解算弹道的逐点多站最小二乘算法得到的弹道精度出发,给出了一个全测速多站系统的最优布站数学模型,并通过大量试算选定了具有良好收敛性的数值算法.初步的计算表明:对全测速多站系统,其最优布站方案与现有布站方案在弹道精度上有着显著的差别;在最优布站方案下可确保逐点多站最小二乘算法具有良好的数值稳定性,并得到满足精度要求的外测弹道.This paper presents an optimal math model of the station-selection of a complete velocity-measuring muhistation system, starting from the trajectory precision computed by using the least-square estimate method for multi-station intersection. The numerical algorithm of the model with good astringency is selected. The primary result of computation indicates that there has been very distinct difference between the trajectory precision of the optimal station-selection and the current station-selection in the complete velocity-measuring muhi-station system, Good astringency of the muhistation least-square estimate method is ensured and the trajectory which fulfills the precision requirement can be obtained by using optimal station-selection.
