数理统计在GPS成果质量检验中的应用

Application mathematical statistics in GPS result's check

针对目前GPS成果质量检验的分析资料较少的现状,以及GPS数据处理软件在使用上仅凭经验而缺乏理论依据的问题,从使用广泛的Ashtech Solutions和Trimble Geomatics Office(简称TGO)软件入手,结合多组GPS静态数据的处理实验,基于数理统计中方差和假设检验的原理,分析解释了基线解算和网平差过程的成果质量检验项目,总结了软件的使用技巧,为内业数据处理提供理论依据和技术手段,并对外业数据采集提供指导和帮助.

Aiming at the present situation that analysis of GPS quality inspection is deficient and the problem that GPS data handling software is used by rule of thumb and lack of theory,starting with the GPS data handling software which is used widely,such as Ashtech Solutions and TGO,combining with experiment of static GPS data processing,based on principle of variance and hypothesis test in mathematical statistics,analyzing and explaining GPS result inspection item in baseline solution and network adjustment,summing-up the skills of using software application,supplying theory and technique for data processing,and providing instruction and helping for data collection.
