Abstract

The invention discloses a flight control method and system based on carrier phase three-dimensional differential positioning, and the method comprises the steps that a first unmanned aerial vehicle tries to obtain correction data of a base station, wherein the correction data comprises data obtained by the base station observing a satellite and position coordinate information of the base station; the first unmanned aerial vehicle releases a broadcast message under the condition that the correction data is not acquired, whrein the broadcast message is used for requesting the correction data; after receiving the broadcast message, the second unmanned aerial vehicle acquires the correction data from the base station; and the second unmanned aerial vehicle sends the received correction data from the base station to the first unmanned aerial vehicle. According to the invention, the problem that the unmanned aerial vehicle cannot obtain the accurate coordinate because the unmanned aerial vehicle cannot obtain the related data of the reference station is solved, and the three-dimensional differential positioning accuracy of the unmanned aerial vehicle is improved.

Description

technical field [0001] The present application relates to the field of unmanned aerial vehicles, in particular, to a flight control method and system based on carrier phase three-dimensional differential positioning. Background technique [0002] The GPS (Global Position System) global positioning system has the characteristics of global coverage, all-weather, and high precision, and has been widely used in all walks of life in the world. In the GPS differential system, the GPS signal receiver is installed on the known coordinate position point, and it is used as a base station receiver. After the base station receiver receives the GPS satellite signal, it calculates the differential correction amount and calculates the differential correction amount It is sent to the user (also called rover) receiver within the service range of the base station to improve the positioning accuracy of the user receiver. According to different differential methods, differential GPS can be div...
