Research On Technology Of Navigation And Positioning For Aircraft Landing

Guiding aircraft landing is an important task in the navigation. With the development of aviation technology, the aircraft’s flight speed, load capacity and endurance are greatly improved, so the problem that the aircraft landing safely need to be solved urgently. This paper proposes a DGPS/INS combination of navigation system to guide the landing.Firstly, introduces the related basics of landing briefly. And then, the paper takes the digital signal processing and the programmable gate array as an information processing board digital platform. Introduces the combination system of data acquisition and processing, including both hardware and software aspects. Navigation information uses the improved adaptive filtering algorithm to fuse, Through the establishment of mathematical models landing, analyzing optimal control of the aircraft’s horizontal and vertical movement, verified the accuracy of the integrated navigation system can meet the requirements of aircraft landing.
