    摘要: A system for interference suppression onboard a satellite includes a beamforming module that processes radio-frequency (RF) signals originated from a plurality of antenna elements of an array antenna to generate multiple analog signals. At least one of the analog signals is an anti-interference signal. Analog-to-digital converters convert the analog signals to a number of digital signals. A processing module processes the digital signals to generate a phase and amplitude control signal. A summation module generates one or more composite signals with reduced interference.

    摘要: A shared beamformer flexibly allocates beams among clusters of beams produced by phased array antenna apertures that are deployed on a satellite (or other type of platform). By sharing the beamformer among the beam clusters, if one beam cluster is not providing useful coverage, the beams may be reallocated to one or more other beam clusters that are providing useful coverage. To share the beamformer among the beam clusters, a selector network is used to select which particular beam cluster (or clusters) is used for producing one or more narrow beams that are constrained to the coverage area of the beam cluster (or clusters).

    摘要: A concentric arrangement of multiple spacecraft antennas mounted symmetrically about the yaw axis of rotation or center of gravity of the spacecraft that provides the capability for spacecraft with multiple antennas to maneuver without introducing errors into navigation signals and without adding complexity to the spacecraft and/or remote terminals. An arrangement of multiple spacecraft antennas comprising a first antenna array mounted on a spacecraft bus, the first antenna array having a center located on a yaw axis of the spacecraft and a second antenna array mounted on the spacecraft bus, the second antenna array having a coincident or overlapping frequency band as the first antenna array and mounted symmetrically about the yaw axis of the spacecraft in a central portion of the first antenna array so as to be concentric with the first antenna array.
