Unmanned aerial vehicle autonomous flight system for multi-source positioning data

Abstract

The invention relates to the technical field of integrated navigation and positioning, in particular to a unmanned aerial vehicle autonomous flight system for multi-source positioning data. The flightsystemcomprises a real-time dynamic differential system. The real-time dynamic differential system comprises a reference station and a moving station; communication connection is established betweenthe reference station and the moving station; the reference station is used for obtaining observation value data, obtaining observation station coordinates, satellite tracking state information and current GPS receiver working state information, and sending the observation station coordinates, the satellite tracking state information and the current GPS receiver working state information to the moving station through a data chain; the moving station is used for receiving data from the reference station while tracking GPS satellite signals, and the data comprises observation value data, observation station coordinates, satellite tracking state information and current GPS receiver working state information. According to the unmanned aerial vehicle autonomous flight system for the multi-source positioning data, the communication connection between the reference station and the moving station can be established, and meanwhile, more forms of monitoring data can be transmitted to the background processing server through the moving station.

Description

technical field [0001] The invention relates to the technical field of integrated navigation and positioning, in particular to an autonomous flight system of an unmanned aerial vehicle with multi-source positioning data. Background technique [0002] The difference technique is to calculate the difference between the observations of one station on two targets, the observations of two stations on one target, or the two observations of one station on one target. The purpose is to reduce the common source of error. [0003] Researchers have found that there are individual UAV autonomous flight systems on the market that can also achieve more precise positioning through real-time dynamic differential functions. Chinese patent CN111679682A discloses UAV landing methods, devices and electronic equipment. Differential methods are used to realize the positioning function of UAVs, but the traditional autonomous flight system of UAVs has a simple system architecture, a single functio...

[0003] Researchers have found that there are individual UAV autonomous flight systems on the market that can also achieve more precise positioning through real-time dynamic differential functions. Chinese patent CN111679682A discloses UAV landing methods, devices and electronic equipment. Differential methods are used to realize the positioning function of UAVs, but the system architecture of the traditional UAV autonomous flight system is simple, the function is single, and the data obtained by it is relatively small, so the positioning accuracy is difficult to be guaranteed.
