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.

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 authors then combined results based on these satellite data with criteria that make forests suitable for pandas, including elevation, slope incline and presence of bamboo.

随后，作者们结合适合大熊猫生活的森林标准，包括海拔高度、边坡坡度以及竹子的分布情况，分析了根据这些卫星数据得出的结果。

But officials said the flights also will serve as a partial replacement for one satellite: NASA's Ice, Cloud and Land Elevation Satellite, known as ICESat.
