Abstract
Abstract A new satellite system configuration is comprised of a power module with rigidly attached solar arrays and a control module including a sun pointing unit, an earth pointing unit and a rotary interface. The power module is attached to one face of the sun pointing unit and an opposite face of the sun pointing unit is attached to the earth pointing unit through the rotary interface to allow the earth pointing unit to remain pointing to the earth while the sun pointing unit rotates relative to it to keep the rigidly attached solar arrays of the power module pointing toward the sun. The earth pointing unit has a docking area for subsequent orbital docking of one or more earth pointing payload satellites to be serviced and controlled by the power and control modules.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
136 words
Satellite system configuration comprising a service satellite (10) including at least one power module (11) having solar arrays rigidly attached thereto, and a control module (12) comprised of a sun pointing unit (1) attached at a first face thereof to one side of the power module, and an earth pointing unit (2) attached at one side to a second face of the sun pointing unit through rotary interface means (3) arranged to allow said earth pointing unit to remain pointing to the earth while said power module and solar arrays are kept pointing to the sun, said earth pointing unit having at least a second side (5) provided with docking means (7) for subsequent docking in orbit of at least one earth pointing payload satellite (20) for being serviced and controlled from said service satellite (10).
Claim 2
Dependent Claim
136 words
Satellite system configuration comprising a service satellite (10) including at least one power module (11) having solar arrays rigidly attached thereto, and a control module (12) comprised of a sun pointing unit (1) attached at a first face thereof to one side of the power module, and an earth pointing unit (2) attached at one side to a second face of the sun pointing unit through rotary interface means (3) arranged to allow said earth pointing unit to remain pointing to the earth while said power module and solar arrays are kept pointing to the sun, said earth pointing unit having at least a second side (5) provided with docking means (7) for subsequent docking in orbit of at least one earth pointing payload satellite (20) for being serviced and controlled from said service satellite (10).
Claim 3
Dependent Claim
59 words
A satellite system configuration according to claim 1, comprising three string legs having a common point, the first leg (100) including the service satellite (10) with said earth pointing unit (2) thereof providing the common point, the other two legs (200, 300) each including at least one earth pointing payload satellite (20,50) docked to said earth pointing module (2).
Claim 4
Dependent Claim
30 words
A satellite system configuration according to claim 2, wherein at least one of said other two legs includes a plurality of earth pointing payload satellites (20,30,40;50,60) docked to each other.
