碩士 === 國立臺灣大學 === 電機工程學研究所 === 90 === This thesis is composed of two research topics in flight. One is path planning of flying vehicle and the other is error analysis of barometric altimeter. The methods of Dijkstra algorithm and dynamic programming are applied to deal with the path-planning problem. Dijkstra algorithm is a special case of label correcting method. The motion constrains of the airplain is considered. Also, waypoints and directions of approaching waypoints will be specified. For a given terrain, the simulation results of the optimal path show that the constraints on flying discussed in the thesis can be satisfied. With the progress of aeronautics and the aviation industry, the barometric altimeter becomes more and more important. Altimeters are very helpful to determine altitude, assess collision risk, and aid GPS positioning. We will analysis the errors and noises in actual flight data which were experimented abroad. We exclude these data associated to the vehicle under the flight phases of climbing, descending, and turning. The obtained errors of the altimeter are associated to the level flight phase. Besides, the noise characteristics of the altimeter are analyzed.
