| 摘要 | An unmanned aerial vehicle (UAV) includes at least one passive reflective device having an elongated configuration defining a long axis and comprising a material configured to reflect radio signals. The UAV also includes a control system configured to control the UAV along a flight path that orients the at least one passive reflective device such that the long axis remains substantially tangential to an ellipsoid whose foci are at two points between which radio communication is desired. | ||
