| 摘 要： | GPS网平差中,平面边长的精度评定是一个很重要的环节,特别是平面边长的相对精度更是决定网平差成果质量的重要指标之一。本文探讨了边长两端点坐标间相关性对评定平面边长精度的影响,并利用某一城市GPS控制网的数据对精度评定结果进行了分析,结果显示:顾及边长两端点坐标间相关性的精度评定方法较为合理。

| Abstract: | The accuracy estimation of plan sides is very important in the GPS network adjustment , especially the relative accuracy of plan sides is a key index , which indicates the quality of GPS control network .The effect of correlation between the termination points of side on the accuracy estimation of plan side is discussed in this paper , a case of city GPS control network is used to analyze the al-gorithm, and results show that the accuracy estimation method considering the correlation of points is more reasonable . |
