A New Method for Detection, Identification and Mitigation of Outliers in Receiver Autonomous Integrity Monitoring (RAIM)

Hiroshi Isshiki

Abstract:	The conventional RAIM based on the least square algorithm of the residuals of the snapshot data can detect the single outlier almost perfectly, but it can miss the multiple outliers. So, it invites a serious problem of the missed detection. We must clarify this problem, and develop a method to prevent the missed detection of the multiple outliers. In the present paper, a method to detect multiple outliers correctly is obtained under the constraint that the outliers are positive, and the numerical results seem reasonable and appropriate.
