INS/DGPS Guide System for Aircraft Precision Approach and Landing

An airborne INS/DGPS guide system is developed in order to ensure an airplane fly straight and precisely over an assigned point,and endow it with the ability of precision approach and landing in complicated weather condition.The system,by effectively integrating INS/DGPS,is not only with high positioning accuracy and working reliability,but also outputs real time and continuous information.Through the deliberate designs of the guide path and guide picture,The pilots would be provided with pictorialized,precise and safety guide information for approach and landing to pilot a plane to decision height even to touchdown.This paper will introdce the system constitution scheme and key techniques as well as flight test results.
