摘　　要：GPS应用于实际控制网数据监测时需要进行坐标的转换,由此产生的误差对于控制网数据处理有较大影响,文章简单分析了当前GPS工程控制网应用现状及其误差影响的主要因素,并在此基础上重点对数据处理误差控制方法进行了探讨,从GPS观测基线合理处理和坐标转换的角度分析探讨了三种坐标系数据处理方法,为进一步提高GPS工程应用于控制网数据处理提供参考。GPS uses needing to carry on the conversion of the coordinate while controlling the network data to monitor actually, therefore there is greater influence in controlling network data processing in the error produced, the article has analysed briefly GPS project controls the main factor that the current application situations of the network and error influence at present, and has controlled the method and carried on the discussion to the data processing error especially on this basis, observe from GPS base-line deal with rationally and angle that coordinate change is it probe into three system of coordinates data processing method to analyse, offer reference for improving GPS project and applying to control network data processing further.
