Abstract
Systems and methods for supporting more flexible coverage areas and spatial capacity assignments using satellite communications systems are disclosed. Antenna elements are arranged in one or more phased arrays. The phased arrays may be used to receive uplink communications, transmit downlink communications, or both receive uplink communications and transmit downlink communications. Beam forming networks (BFN's) associated with the one or more phased arrays may be dynamic, allowing for movement of the locations of the receive beams, the transmit beams, or both the receive beams and transmit beams. The beams may then “hop” from location to location according to a predefined or dynamic hopping pattern. In some embodiments, the hopping patterns may be time-varying and may be changed or updated on-the-fly.
