Development of a New RAIM Algorithm for GPS Applications I

GPS 응용을 위한 새로운 RAIM 알고리즘 개발 I

RAIM techniques based on TLS have rarely born addressed because TLS requires a great number of computations. In this paper, the special form of the observation matrix H, that is, one column is exactly known, is exploited so as to develop a new TLS-based sequential algorithm to identify an errant satellite. The algorithm makes us enjoy the advantages of TLS with less computational burden. The proposed algorithm is verified through a numerical simulation.
