区域GPS网数据处理

Data Processing of Regional GPS Networks

分析了运用由广州中海达公司研发的HDS2003数据处理软件对小区域GPS网静态观测数据进行处理的过程。在数据处理过程中对不符合精度指标的基线进行了处理,以满足接下来的网平差条件;进行网平差后,通过x^2检验和τ检验来检验平差结果是否满足精度要求,并对其不合格的原因采取相应的措施来解决,以保证观测数据的精度要求。

This paper analyses the data processing of regional static GPS networks using HDS2003 data processing software developed by the ZhongHaida Guangzhou Company.Treating with the baseline which is falling short of the precision target in order to satisfy the following networks adjustment;after the adjustment, using x^2 andτcalibration to check up the results,then analyses and takes action to the failing results in order to ensure the data accuracy requirements.
