INERTIAL SMOOTHING AND EXTRAPOLATION OF ILS BEAMS

One of the problems of automatic approach and landing is the accuracy of aircraft guidance as the aircraft flies along the ILS Beams. The system studied here can smooth the Loc data and ensure continuation of aircraft guidance in the event of a Localizer failure. This system only needs complementary speed information from an inertial sensor system in order to provide the auto-pilot with a filtered Loc signal instead of the raw signal. The final system, based on Kalman filtering, was implemented by means of a digital computer, then flight tested on the AIRBUS A. 300. B. Certification of this system with reduced operational visibility minima is expected in the Spring of 1978.
