  • Low-cost multi-mission broadband communications payload
    Patent number: 6628919
    Abstract: A method and system for communicating using satellites in a constellation in LEO, MEO or GEO orbits is disclosed. The system comprises a receive system, a downlink system, and a data processing system. The receive system receives an uplink signal comprising at least one data packet from at least one user in an uplink cell. The ground programmable downlink system transmits the data packet to a specific downlink cell and adjusts a power used to transmit the data packet to the specific downlink cell. The ground programmable data processing system processes and routes the data packet to an input of the downlink system such that the downlink system transmits the data packet to the specified downlink cell.
