仿真结果表明用户和基准台之间距离增大和低卫星仰角都将使伪距残差增大，气象因素和高程对伪距残差也有影响。

The simulation results indicate that the pseudo-range remaining errors will be increased with the distance between base-station and GPS user and in the case of low satellite elevation.

本文利用全阴影模型的研究结论，就实际陆地移动卫星信道部分阴影模型的仿真问题，拟合了模型参数与卫星仰角之间的关系。

These research results have been used to design the partial shadow model for simulating the same channel of LMS. The author fits the curves between the model parameters and satellite elevations.
