Statistical approach to satellite navigation integrity monitoring

Abstract

One of the most important challenges for a satellite navigation system (GPS, GLONASS, future GALILEO, etc) is its integrity monitoring for safety critical applications. Integrity monitoring requires that the navigation system detects, isolates faulty measurement sources, and removes them from the navigation solution before they sufficiently corrupt the output. The principal limitation of the conventional “snapshot” RAIM FDE algorithms based on the least squares algorithm is a low availability of its detection and especially exclusion functions. This problem becomes crucially important when the RAIM has to be used to provide integrity for safety-critical applications like the aircraft guidance with the vertical positioning information or the safe train positioning.
