Abstract
A communication system ( ) utilizing a constellation ( ) of satellites ( ) is presented. A source ground station ( ) transmits an uplink signal ( ) containing source payload data ( ) to a primary satellite ( ) located in an orbit ( ) about the Earth ( ). The primary satellite ( ) conveys the source payload data ( ) to a secondary satellite ( ) located proximate the primary satellite ( ) in the orbit ( ), where the source payload data ( ) is baseband processed to produce destination payload data ( ), which is then conveyed back to the primary satellite ( ). The primary satellite ( ) transmits a downlink signal ( ) containing the destination payload data ( ) to a destination ground station ( ). The primary satellite ( ) and secondary satellites are configured to expend majorities of their energy budgets in downlink transmissions and payload data processing, respectively.
