Methods and apparatus for using ground based processing resources to support orbiting satellites

摘要

A plurality of orbiting satellites (102-112), each comprised of an onboard computer (142). Each of the orbiting satellites and a plurality of ground-based computers (114-124) are utilized to perform delay-insensitive functions associated with the orbiting satellites. An ubiquitous data link (128-138) is maintained between each satellite and one or more of the ground-based computers. The integrated system is configured to allow a satellite to generate a remote procedure call (RPC), transmit the RPC to a ground-based computer, whereupon the ground-based computer processes the RPC and transmits a response back to the satellite. Delay-sensitive tasks and functions are performed by the computer onboard the satellite; delay-insensitive tasks are advantageously performed by the ground-based computer assets.
