Preliminary Research on Remote Planning Methods for Paths of Unmanned Aerial Vehicles in the Safe Aerial Corridor

Opening of the low altitude airspace is imperatively driven by the great economic prospect. As a result, the low-altitude, slow and small (LSM) moving targets like unmanned aerial vehicles (UAVs) will cause hidden dangers to ground facilities, social order and living of people. This accordingly urges development of effective technologies to solve the problem. Different from ground vehicles' route planning, UAVs emphasize more on ground remote planning of paths in the safe aerial corridor. This paper presents preliminary research on this aspect. It firstly proposes a remote planning service structure based on WebGIS (Geographic Information System Based on Internet), then establishes modeling for planning space and its associated objects with reference to specific example, thirdly simulates and analyzes limitations of the structure and makes pertinent improvements to it using ant colony algorithm based 3D safe corridor planning method so as to meet strict requirements from air traffic control on minitype UAVs, and finally summarizes the research findings and renders future research highlights in this field.
