    • Systems and methods configured to form and point beams from an unmanned aerial vehicle (UAV) toward target cells in a coverage area on the ground. One embodiment determines and forms the required number of UAV fixed beams needed to cover the target area when UAV is at its highest altitude and highest roll/pitch/yaw angles so that the target coverage area is covered under ail UAV altitude and orientation conditions. In another embodiment, UAV determines the beam pointing angles toward different cells on the ground using information on position coordinates and orientation angles of the UAV, and the position coordinates of the cells in the coverage area relative to the center of coverage area. In another embodiment, a reference terminal placed at the center of coverage is used by the UAV to optimally point a beam toward center of the coverage area.
    • 系统和方法被配置成形成并将来自无人驾驶飞行器(UAV)的波束指向地面覆盖区域中的目标小区。 一个实施例确定并形成当UAV处于其最高高度和最高的滚转/俯仰/偏航角时覆盖目标区域所需的UAV固定波束所需数量,使得目标覆盖区域覆盖在UAV的高度和方向条件下。 在另一个实施例中,UAV使用关于UAV的位置坐标和取向角度的信息以及相对于覆盖区域的中心的覆盖区域中的小区的位置坐标来确定朝向地面上的不同小区的波束指向角度。 在另一个实施例中,UAV使用放置在覆盖中心的参考终端将波束最优地指向覆盖区域的中心。
