A New Sequential RAIM Algorithm for Multiple Failures Detection

Ho Yun and Changdon Kee

Abstract:	This paper develops and analyzes a new RAIM algorithm as a candidate of future architecture of RAIM algorithm which can treat not only a single failure but also simultaneous multiple failures. A proposed algorithm uses measurements residuals and satellite observation matrices of several consecutive epochs for multiple Failures Detection and Exclusion (FDE). It can detect multiple failures without limitation of number of faulty measurements or types of failures. In this paper, we give detailed explanation of the FDE algorithms with rigorous mathematical expression. Simulation results show that detection capability of the proposed algorithm is superior to conventional multiple hypothesis RAIM algorithms.
