关于商用GPS平差软件相关问题的分析

Analysis on the Related Problems of Commercial GPS Adjustment Software

GPS定位技术测量精度高、效率高,广泛应用于控制测量中,各种型号的GPS接收机的测量数据一般使用其随机所带的商用平差软件进行平差计算,但均与现行的《全球定位系统(GPS)测量规范》相关要求存在不一致的情况。本文结合实际测量案例,从GPS控制网平差入手,探讨分析商用GPS平差软件计算结果在数据质量检核方面与国家标准要求不一致之处,并提出合理的解决方案。

GPS positioning technology has high measurement accuracy and efficiency,and is widely used in control measurement.The measurement data of GPS receivers of various models are generally calculated by commercial adjustment software,which is carried with it.However,there is inconsistency in the relevant requirements of the current GPS Measurement Specification.In this paper,combined with the actual measurement cases,starting with GPS control network adjustment,the author discusses and analyzes the inconsistency between the calculation results of commercial GPS adjustment software and the national standard requirements in data quality inspection,and puts forward reasonable solutions.
