Abstract

RAIM (Receiver Autonomous Integrity Monitoring) is an autonomous integrity monitoring technology which fulfills the fault's detection and isolation of the navigation solution in a receiver, based on the redundancies of observations. It has been widely concerned and studied for the short warning time, the ability of detecting local user failures, and no need of additional hardware resources and complex communication links with ground stations. The fundamental of RAIM is introduced, and the key technologies such as methodology, availability, application and combination of RAIM with other integrity technologies are summarized and analyzed. With the constructing of new generation GNSS systems, RAIM's application is getting broader and broader. To improve RAIM technology and its availability, the future studies should be concentrated on RAIM availability's augmentation, multi-failures monitoring algorithms, compatible systems' RAIM and its availability and RAIM algorithms' extension.
