| 摘 要： | 摘要：针对纯方位交叉定位中存在着地球曲率对定位精度影响的问题本文提出了基于正北方向修正和椭球模型两种定位算法。通过与传统的交叉定位算法比较，可以看出这两种算法具有较好的定位精度。在理论上分析了测量误差和观测站位置误差对定位精度产生的影响，给出了几何精度因子（GDOP）的理论推导和仿真结果。

| Abstract: | Considered the positioning accuracy affected by earth curvature for bearing-only location system, based on north-calibrated location algorithm and ellipsoid model of global location algorithm are presented in this paper. Compared with the traditional cross-location algorithm, the algorithms have good position accuracy. The effect of measure error and position error are theoretically analyzed, also the expression of GDOP and simulation result are shown. . |
