UAV monitoring method and system based on Beidou satellite

Abstract

The invention relates to the technical field of unmanned aerial vehicle communication, in particular to an unmanned aerial vehicle monitoring method and an unmanned aerial vehicle monitoring system based on Beidou satellite. The monitoring method comprises the following steps that the positioning information and the posture information of an unmanned aerial vehicle are obtained; Beidou short messages are generated according to the positioning information and the posture information in accordance of a Beidou short message protocol standard; the Beidou short message communication technology is utilized for transmitting the Beidou short messages to ground receiving equipment through the transferring by the Beidou satellite; the ground receiving equipment analyzes the positioning information and the posture information in the Beidou short messages, and in addition, the unmanned aerial vehicle monitoring is carried out according to the positioning information and the posture information obtained through the analysis. The unmanned aerial vehicle monitoring method and the unmanned aerial vehicle monitoring system based on Beidou satellite provided by the invention have the advantages that the coverage range of a Beidou satellite communication system is about east longitude 70 degrees to 140 degrees and northern latitude 5 degrees to 55 degrees, the signal coverage area is improved, the problem of limitation of the monitoring on the unmanned aerial vehicle by distance is solved, and the effectiveness on the monitoring of the unmanned aerial vehicle is improved.

Description

technical field [0001] The present invention relates to the technical field of unmanned aerial vehicle communication, in particular, to a monitoring method and system for unmanned aerial vehicles based on Beidou satellites. Background technique [0002] UAV (UnmannedAerialVehicle, abbreviated as UAV) is an unmanned aircraft that is controlled by radio remote control or its own program. During the flight of the UAV, it is necessary to monitor the operating status of the UAV. [0003] In related technologies, the operating status of the drone is mostly monitored through the drone measurement and control system. The monitoring of the operating state of the UAV by the UAV measurement and control system mainly includes: obtaining the position information and attitude information of the UAV; transmitting the acquired position information and attitude information to the ground monitoring terminal; further, the ground monitoring terminal sends The drone issues control commands.

Problems solved by technology

[0004] However, because the transmission power of the radio antenna is limited, the communication distance between the UAV and the ground monitoring terminal is limited. If the distance between the UAV and the ground monitoring terminal exceeds the effective communication distance, the UAV cannot be monitored.
