The use of the GPS (Global Positioning System) satellite system in the aviation world is as a navigation system. In its application as a civil aviation navigation system, there are three main concerns, namely system accuracy, operational integrity and continuity of GPS availability. Because the GPS signal is degraded especially due to Selective Availability, integrity becomes a critical factor in navigation, considering that this parameter is directly related to flight safety. RAIM is an internal integrity monitoring technique, which is an error detection algorithm in the GPS system by checking the consistency of observation data. The integrity monitoring system with RAIM consists of error detection functions and detection power monitoring, which are influenced by the quality and geometry of the measurement. With this function, the system will notify the user whether the aircraft is navigating in normal conditions, failure, false alarm or missed detection. RAIM performance will be optimal if there is a guarantee of RAIM availability, where the number of observations is sufficient. One of the efforts that has been tested is to integrate the GPS system with GLONASS, the GIC external integrity monitoring system, barometric altimeter and the addition of a receiver clock function. In this thesis, we discuss the basic algorithms for error detection, namely the Least Squares Residuals and Parity Space methods, and the integrated GPS system.
