摘要： An actuator gearbox includes a drive shaft including a plurality of gear linkages that are spaced apart along the drive shaft, and a plurality of output shafts adjacent respective ones of the plurality of gear linkages. Each of the gear linkages includes a fixed gear coupled to one of the plurality of output shafts and a moving gear that is slideably coupled to the drive shaft. A bias spring is coupled to the moving gear to urge the moving gear out of engagement with the fixed gear. The mechanical switch moves the moving gear into engagement with the fixed gear on the output shaft adjacent the linkage to thereby cause the output shaft to rotate in response to rotation of the drive shaft.

摘要： A transmission antenna unit includes a plurality of transmission antennas, a reception antenna unit, and a processor. The plurality of transmission antennas that are arranged in a row along a predetermined array direction. The reception antenna unit includes a plurality of reception antennas that are arranged in a row along the array direction. The plurality of transmission antennas and the plurality of reception antennas form a virtual array in which a plurality of virtual reception antennas are arranged in a row along the array direction. The processor corrects a plurality of virtual reception signals by multiplying a virtual reception signal matrix by an inverse matrix of a reception mutual coupling matrix and an inverse matrix of a transmission mutual coupling matrix.

摘要： Methods, apparatuses, and systems for two-way satellite communication and an asymmetric-aperture antenna for two-way satellite communication are disclosed. In one embodiment, a beam pattern for an asymmetric-aperture antenna is offset in a narrow beamwidth direction, and the offset beam pattern is directed by a mechanical gimbal, with the beam pattern offset made to reduce interference with an adjacent satellite. In additional embodiments, operational areas near the equator are identified for a given offset beam pattern, or a beam pattern offset may be adjusted over time to compensate for movement of the asymmetric-aperture antenna when attached to an airplane, boat, or other mobile vehicle.
