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. The method comprises receiving at the satellite an uplink signal comprising at least one data packet from at least one user in an uplink cell, processing the data packet on the satellite, routing the data packet to a transmit antenna on the satellite, adjusting a power level of a transmitter used to transmit the data packet from the satellite to a specific downlink cell, and transmitting the data packet to the specified downlink cell.
