Unmanned aerial vehicle antenna system, unmanned aerial vehicle and unmanned aerial vehicle system

The invention provides an unmanned aerial vehicle antenna system, an unmanned aerial vehicle and an unmanned aerial vehicle system. The unmanned aerial vehicle antenna system includes a satellite antenna and a six-degree-of-freedom parallel motion mechanism, wherein the satellite antenna is used for communicating with a remote control device of the unmanned aerial vehicle through satellites, and the satellite antenna is arranged on the six-degree-of-freedom parallel motion mechanism. When the unmanned aerial vehicle is in flight, the orientation of the satellite antenna is adjusted by rotating the six-degree-of-freedom parallel motion mechanism, thereby making it possible for the satellite antenna to communicate with the satellites, changing the communication mode of the unmanned aerial vehicle with a ground command center, and being applicable to long-distance flight. 本发明提供一种无人机天线系统、无人机和无人机系统，包括：卫星天线和六自由度并联运动机构；其中，卫星天线用于通过卫星与无人机的远程控制装置通信，卫星天线设置在六自由度并联运动机构上；在无人机飞行时，通过转动六自由度并联运动机构以调整卫星天线的朝向，使得卫星天线可以与卫星通信，改变了无人
