摘要
本文利用矩阵为工具 ,采用最佳估计原理 ,从理论上证明了几何精度因子随岸台数目的增加而减小。从一种导航定位误差的数学分析方法中引进一个普遍适用的几何精度系数的概念和新的最优岸台选址设计算法 ,并利用GDOP(GeometricalDilutionofPrecision)得出了导航定位误差的简单估计和分析所选岸台的最佳配置 ,此算法使得导航定位误差的分析既统一又简单 。
This paper proves, in theory, that GDOP decreases as the number of radio launch pads increases by optimum estimation and matrix. A general used conception of GDOP coefficient and the algorithm about how to optimize the positioning of radio launch pads are derived from the method of mathematic analysis on navigation fixing error. The analysis is made about the location features of the located radio launch pads based on GDOP.The algorithm makes it unitive and easy to analyse the navigation fixing error, in the research field of which it is valuable for theory and practice.
