In order to enhance satellite navigation system's capability of estimating arrival direction of jamming, power inversion, space-time least-mean-square, multiple signal classification and its improved algorithm were applied to estimate arrival direction of jamming on independent and interrelated jamming respectively.The results show that:under the independent case, estimation error of power inversion and space-time least-mean-square algorithm is 2°~3°, while it is precisely estimated by multiple signal classification and its improved algorithm.Under the interrelated case, multiple signal classification and space-time least-mean-square algorithm are disable, and it is difficult for power inversion algorithm to identify the jamming, whereas, estimation error of the improved multiple signal classification algorithm is 2°which will enhance arrival direction veracity of jamming effectively.
