Understanding RAIM for IFR Operations by bft23 is a document available to read on EtoBox.
RAIM (Receiver Autonomous Integrity Monitor) is software in aviation GPS receivers that monitors for faults in GPS satellite signals and warns pilots if the accuracy is degraded. It is important for safety when flying under IFR. RAIM works by using redundant position solutions from visible satellites to detect outliers. Loss of RAIM availability triggers warnings and means GPS cannot be used for navigation on approaches. Modern systems perform fault detection and exclusion to remove bad satellites from posi
