The invention relates to the technical field of unmanned aerial vehicle ground facilities, in particular to an unmanned aerial vehicle navigation and positioning system. The ground following module comprises a limiting ring; the conveying pipe is used for conveying the functional liquid in the ground following module to the unmanned aerial vehicle; the detection module comprises a pressure sensor which is arranged on the limiting ring in the circumferential direction and used for detecting the collision frequency of the conveying pipe and the limiting ring, and a displacement sensor which is arranged at the position, intersecting with the plane where the limiting ring is located, of the conveying pipe and used for detecting the moving distance of the conveying pipe in the limiting ring; the positioning module adjusts the flight speed of the unmanned aerial vehicle and the output length of the conveying pipe according to the collision times and the moving distance; the flight direction of the unmanned aerial v
