Multisensor Signal Processing Techniques (Hybrid GPS/LORAN-C with RAIM)

Abstract

One of the major elements in alleviating existing problem in en route airspace is to allow more aircraft to traverse a given volume of airspace. Recent developments in navigation systems will support this effort by enabling user preferred routes and by offering more precise and reliable navigational capabilities. Multisensor navigation system architectures are presented with the emphasis on signal processing techniques and receiver autonomous integrity monitoring (RAIM). This is followed by a detailed study of a hybrid navigation receiver based on the NAVSTAR Global Positioning System (GPS) and the Long Range Navigation System LORAN-C. The design, implementation and flight testing of a prototype hybrid GPS/LORAN receiver are presented, including the realtime simulation and detection of navigation signal malfunctions.
