Classification: CPC H | IPC H

Claim 8:
9. A system configured to support direct communication between a set of discrete satellite modules operating in low Earth orbit (LEO) and forming a distributed phased-array antenna with a single aperture and a set of end user devices, the system comprising:
one or more processors operatively coupled to memory that is configured to store information including at least one of communication link frequency assignments, beam mapping, or satellite constellation ephemeris information, the one or more processors being configured to:
perform, based on the stored information, Doppler compensation to a center or substantially center of each beam that provides communication between the set of end user devices and the distributed phased-array antenna operating in LEO, wherein each beam is associated with a corresponding cell of a set of cells according to the single aperture, so that a Doppler shift for each beam as seen by a respective end user device of the set of end user devices that is in a given one of the set of cells falls below 1200 Hz; and
perform, according to the stored information, delay compensation to the center or substantially center of each beam in the given cell so that a delay as seen by the respective end user device of the set of end user devices is below 0.5 ms.
