| 摘 要： | 根据部分最小二乘平差原理把观测值按照是否含有粗差分成两组，对含有粗差和不含粗差组分别实施最小二乘平差，从而实现粗差的定位定值。针对原部分最小二乘平差法在分组时速度慢、效率低的缺点，利用观测值改正数的特点，改进了分组方法，从而加快了分组速度，提高了粗差探测效率。

| Abstract: | According to the principle of partly least squares, the observed values according to whether they contain gross errors were divided into two groups. Containing gross errors and non groups were implemented least-squares adjustment, in order to achieve gross error location and estimation~ For the shortcomings of original partly least squares, this paper use the features of observations＇ corrections to improve grouping method and gross error detection efficiency. |
