Tethered airborne communications and information transfer system

摘要: A tethered balloon including means for controlling the height thereof is utilized as an airborne platform transmitting and receiving apparatus a multiple antenna assembly. The assembly suspended from gimbal or ball joint configuration attached to so that it gravity stabilized in vertical plane. itself comprised of plurality independently rotatable coaxial shafts having respective coupled thereto. are hung pendulum arm member which freely moveable within cone angle limit 45* maintains orientation + OR - 2*. rotation each controlled ground station by control signal selectively point predetermined compass direction. Additionally, shaft couples transmitter-receiver its order provide selective transfer between and/or other similar systems.
