Abstract:One of the major elements in alleviating existing problems 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.
Multisenor 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.
