Document Type and Number:
WIPO Patent Application WO/2019/119237
Kind Code:
A1
Abstract:
Disclosed in the present invention are an unmanned aerial vehicle and a circularly polarized antenna assembly of the unmanned aerial vehicle. The unmanned aerial vehicle comprises a body, a real-time kinematic (RTK) assembly, and a circularly polarized antenna assembly provided at the top of the body, wherein the circularly polarized antenna assembly is used for receiving a satellite signal, and the RTK assembly is used for determining position information of the unmanned aerial vehicle according to the satellite signal received by the circularly polarized antenna assembly and RTK data obtained from a RTK base station. The unmanned aerial vehicle performs positioning by using RTK technology, and the positioning accuracy is improved. Moreover, the unmanned aerial vehicle in the present embodiment receives a satellite signal by using a circularly polarized antenna, and the circularly polarized antenna is small in size and light in weight, so that the size of the unmanned aerial vehicle is reduced and the endurance of the unmanned aerial vehicle is increased.
