Abstract

The invention relates to the field of civil aviation navigation equipment online monitor and flight verification for drones, in particular to a drone positioning method and a drone positioning systemfor flight verification. The drone positioning method includes according to reference carrier phase observation quantity of ground standard position information and position carrier phase observationquantity of drone flight routes at a same moment, acquiring three-dimensional drone position data at the moment by a GPS (global positioning system) on a drone; according to initial position information of the drone at a preceding moment, calculating the three-dimensional drone position data at the moment by an INS positioning system on the basis of data of a gyroscope, an acceleration sensor andthe like; by a central processor on the drone, according to the number of satellites involved in the three-dimensional drone position data of a GPS positioning processor at the moment, deciding whether to adopt the three-dimensional position data of the INS positioning system or the three-dimensional position data acquired after fusion of the INS positioning system and the GPS as the final three-dimensional drone position data to perform real-time positioning of the drone.
