Burnashev V.V. System of navigation and control of unmanned airplane for automatic landing. - Manuscript. Thesis on competition of candidate of technical science degree on specialty 05.11.03 - Gyros and navigational systems. - National technical university of Ukraine "Kiev polytechnic institute", Kiev, 2012. In dissertation the problem of navigation system exactitude definition necessary for fulfillment of an unmanned airplane automatic touchdown on a landing gear is solved. Trajectories of automatic touchdown are designed. Thus the approach to the problem solution of a determination of the airplane nominal flare path, ensuring desirable flight parameters values in tangency point. The mode of the autoflare program shaping, permitting to reduce an air part of the landing distance, and also to improve the stabilization quality. Laws of the airplane stabilization are designed for landing trajectories by methods of analytical designing and Hinf- theory. In view of a flare path shaping mode performances limitations of navigation and attitude system as the inequalities containing measurement errors and errors of stabilization of motion parameters are obtained. On their basis the technique of definition of navigation and attitude system required exactitude according to which performances of a navigational system for unmanned airplane the FAKS-1 are designed is offered. The structure of the meters ensuring designed perform-ances at use weakly-bound integration scheme is chosen. It is executed semi-real modeling of a navigational system for the unmanned airplane making automatic touchdown, controlled on its signals. Key words: automatic touchdown of an airplane, a flare path, analytical designing, errors of stabilization, navigational system exactitude.
