摘要
在GPS静态数据处理的过程中,卫星截止高度角对数据处理时采用的卫星数目、数据质量有着显著影响。本文采用TEQC、TBC、GMAIT三款高精度数据处理与分析软件,通过设置不同的卫星截止高度角,来分析其对GPS基线质量的影响。对卫星截止高度角对GPS基线质量的影响特点以及如何通过卫星截止高度角来提高基线质量,给出了相应的结论与建议。
In the process of GPS static data processing,the satellite cut-off height angle has a significant impact on the number of satellites and data quality used in data processing. This paper used TEQC,TBC,and GMAIT three high-precision data processing and analysis software to analyze the impact of GPS baseline quality by setting different satellite cut-off height angles. The influence of satellite cut-off altitude angle on the quality of GPS baseline and how to improve the quality of baseline by satellite cut-off altitude angle are discussed,and the corresponding conclusions and suggestions are given.
