摘要
该文提出一种区域定位系统n个地面测站的布站策略,给出4测站时几何精度因子计算公式,从而可快速获得最佳定位点位置。由于公式不涉及矩阵乘法和求逆运算,因而计算量较小。
This paper presents the arrangement strategy of ground stations for a regional positioning system and derives the formulas for calculating GDOP with 4 grounds stations. With the flying users＇ known altitude, the highest positioning precision can be acquired quickly. Since the formulas do not involve the multiplication and inverse of matrix, the calculations are reduced.
