Unmanned Aerial Vehicle Landing Method Based on BeiDou Relative Navigation Technology

Unmanned aerial vehicle (UAV) technology is rapidly developing and application, and UAV recycling is the key link in the application according to statistics, 80% of UAV failures occurred in the process of landing. Traditional UAV recycling methods have been unable to meet the modern UAV use. With the rapid development and application of BeiDou Navigation Satellite System (BDS) in China, using BDS to realize automatic control of UAV becomes a new hot research topic. This paper presents a UAV landing recycling scheme based on BDS relative navigation technology and studies its key technologies. Adding MEMS inertial information to assist BDS improves its accuracy and enhances the feasibility and practicability of the scheme. The dynamic to dynamic positioning experiment verifies the reliability of key technologies and shows that the relative positioning technology proposed in this paper meets the requirements of automatic landing of UAVs and proves that the automatic landing of UAVs is feasible.
