应用序贯平差法探粗差

给出了序贯平差探测粗差原理，算例表明，该方法对粗差具有较强的发现能力，存在多个粗差时，采用逐步探测法，可逐个探测粗差。还给出了相关观测转换为２组相互独立观测值的一种算法，使相关观测也能进行序贯平差。

STUDY ON DETECTION OF GROSS ERROR BY SUCCESSIVE ADJUSTMENT

The principle of detecting gross errors by successive adjustment is given in this paper. It is shown that the new method has a good capability to detect gross errors. When there are more than one gross error. a good result can be obtained by using the method of detecting gross error one-by-one with successive adjustment. A new algorithm is put forward, through which the correlation observation can be trasformed into two or more independent sets, and then the successive adjustment can be carried off and gross errors can be detected with correlation observation.
