Aerospace Instrument-Making Annotation << Back Path planning for purposeful fl ight of an autonomous aircraft at low altitude in uncertain environment Melekhin V.B., Khachumov M.V. Algorithms for planning locally optimal routes for the purposeful low-altitude flight of an autonomous aircraft in the presence of obstacles are proposed. We assume that the map of the area is a priori not known and decisions are made only on the basis of information coming from the environment in real time. Decision making lies in calculating route trajectories for purposeful fl ight at a certain altitude. This makes it possible to solve the problems of motion planning for an aircraft in real time for both stationary and dynamic goals. Key words: unmanned aerial vehicle, motion planning, obstacles avoidance, uncertain environment, pursuit of the goal. Contacts: E-mail: pashka1602@rambler.ru, E-mail: khmike@inbox.ru Pp. 18-27.
