| 摘 要： | 本文对几种不同粗差定位方法的适用范围进行了分析,提出了一种新的权函数公式,并在某边铁控制网中进行了实验。结果表明,在测边精度不同且存在多个粗差的情况下,本文提出的带权数据探测法能有效地确定所有含有粗差的边长观测值和角度观测值的位置,效果很好。

| Abstract: | This paper analyzes the application scope of several gross error detection methods and formulates a new weighting function. The function is tested in a combined framework of control of triangulation and trilateration. The result is fine, which shows that the data snooping method with the new weighting function can locate all the measurements with blunders of the framework accurately and effectively in the case that the accuracy of distance measurements are different and a few blunders coexist. |
