A trajectory planning method for long-distance transition flight at low altitude

Abstract

The invention discloses a route planning method for low-altitude medium- and long-distance ferry flights. The route planning method can plan a flight route with minimum flight cost for an aircraft, and multi-aircraft and multi-route collaborative task planning can be achieved herein. The route planning method is characterized in that a route is divided into a route-entering path P1, a flight path P2 and a route-exiting path P3; the route-entering path P1 and the route-exiting path P3 employ the shortest distances avoiding static threats; the flight on a flight path is a flight performed below a planned civil aviation route, and the shortest flight path is found by utilizing DijKstra algorithm; multiple aircrafts fly in a simulated manner on a digital map according the planned basic route; safety detection and warning are performed according to the current flight states of the aircrafts and the preset environment information on the digital map, and warning information is output; route optimization is finally performed according to the warning information.

Description

technical field [0001] The invention relates to the technical field of track planning, in particular to a track planning method for long-distance transition flight in low altitude. Background technique [0002] As my country's low-altitude airspace management reform enters the substantive operational stage, the general aviation industry is facing strategic development opportunities. In the matching traditional air traffic control system, there are the following three problems: first, it is necessary to manually find the highest obstacle around the route and calculate the minimum flight safety altitude; second, it is necessary to manually collect the flight airspace, navigation station, and location The airspace environment conditions such as reporting points and alternate landing sites; the third is the failure to achieve multi-vehicle, multi-track collaborative mission planning. In order to solve the above practical problems restricting the development of general aviation,...
