Claim 0:
1. A station 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 station comprising:
memory configured to store information including at least one of communication link frequency assignments, beam mapping, or satellite constellation ephemeris information; and
one or more processors operatively coupled to the memory, 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 devices 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 devices of the set of end user devices is below 0.5 ms.
