摘要： A device is provided for the accurate positioning of an antenna of a satellite in space, in which the antenna is fastened to a plate mounted on gimbals, with the plate capable of being swiveled around two axles supported in bearings and extending vertically to one another. A rotary drive is provided for each axle, said rotary drive consisting of an arm of a lever, said arm being connected to the axle, and a linear drive that freely affects the arm.

摘要： An antenna system adapted to be mounted on an exterior surface of a mobile platform and having a reduced overall height to reduce aerodynamic drag caused by the antenna system. The antenna system includes a movable platform disposed concentrically within an annular stationary platform. The movable platform includes a slip ring assembly formed on its lower surface which is in physical contact with a brush assembly supported from a lower surface of the stationary platform. By locating the slip ring assembly and the brush assembly adjacent the lower surface of the movable platform, the overall height of the antenna is reduced. Reliability is also improved since contaminants are less likely to accumulate on the slip ring assembly due to its presence on the lower surface of the movable platform.

摘要： An antenna arrangement comprising an antenna reflector (10) and a transceiver horn (11) combined to form a compact unit (10-11) includes a dynamic vibration-dampened suspension device (16), first (12) and second (15) rotation frames, and first (13) and second (15) elevation frames. The frames are rotatably mounted at the periphery of respective suspension device or frame, with the first rotation frame (12) mounted on the periphery of the suspension device and with the second rotation frame (15) mounted on the periphery of the second elevation frame (14) and functioning as an attachment for the compact antenna unit (10-11). The requisite bearing points are hereby moved to the periphery of the antenna arrangement and space is made available for accommodating the compact antenna unit (10-11) in the center of the suspension device.
