进一步分析了雷达辐射源位置、星座几何形状和星座的卫星高度对几何精度衰减因子的影响。

Then, the effects of radar beacon position, cluster geometry and satellite altitude on the geometry dilution of precision factor are analyzed.

几何精度衰减因子gdop和卫星信噪比SNR等多方面因素的影响，增大了GPS单点定位误差。

GPS positioning accuracy is influenced by Geometric Dilution of Precision (GDOP), Signal Noise Ratio (SNR) and so on.

该方法同时考虑了参数误差与几何淡化因子对定位精度的影响，不需要矩阵求逆，运算量小，速度快。

The method is characterized by light computational load and short time because it does not need to calculate the inverse of matrix.
