摘要
GPS观测数据之间大多存在比较强的相关性,同时还包含粗差、系统误差及偶然误差。传统的方法是利用先验方差阵进行经典平差,提出在保持相关观测量间相关性不变的条件下,用标称精度改正权进行经典平差,通过实验数据分析和比较,采用此方法对GPS网进行平差可取得满意的结果。
Mostly, there is strong relevance among the GPS observation data; at the same time, it also includes blunder, systematic error and random error. The conventional method is using the transcendental variance to make classical adjustment, The paper puts forward marking and claiming precision to correct the weight , and then adjusts the network by comparing and analyzing the experiment data, believing that adopting this method to adjust GPS network can get satisfactory results.
