不同截止高度角对GAMIT基线解算的影响分析

Effect of Different Cut-off Elevation Angles on GAMIT Baseline Solution

为了分析不同截止高度角对基线解算的影响,以及选择最合适的截止高度角来进行GNSS数据处理,本文选取中国及周边11个IGS站2013年第102~117天的16天数据,通过GAMIT软件解算不同截止高度角条件下的基线结果,通过对比分析,得出当截止高度角取10°~15°时,基线解算结果最佳。

In order to analyze the effect of different cut off el- evation angles on baseline solution, and to select the most appropriate cut off angle for GNSS data processing, this pa- per selects 16-day data of 11 IGS stations in China from 102th to l17th of 2013. By using GAMIT for decoding base line results under the condition of different cut-off elevation angles, comparison and analysis results show that baseline solution result is the best when the cut off elevation angle is 10°-15°.
