GPS姿态解算中基于RINEX格式的数据处理

RINEX Based Data Processing in GPS Based Attitude Determination

介绍了 GPS RINEX交换格式的发展与构成 ,分析了基于 RINEX格式的两种主要的观测数据文件和导航信息文件的内容与特征。基于一个 GPS姿态测量试验 ,实现了姿态解算中参考卫星的选取和载波相位双差的解算 ,为进一步的姿态解算建立了基础。处理结果表明了 RINEX格式在 GPS数据处理中的方便与高效性。

The development and structure of GPS RINEX exchange format are introduced firstly.Based on it,contents and characteristics of two main observation data file and navigation message file are discussed and analyzed.Selecting reference GPS satellite in attitude determination and double differencing of carrier phase measurements are implemented based on a attitude determination test with GPS,and the foundation for the further attitude determination is formed.The processing result shows the convenience and efficiency of RINEX in GPS data processing.
