  • Reduced cost mobile satellite antenna system using a plurality of satellite transponders
    Patent number: 7925232
    Abstract: A system for utilizing circular polarized signals to perform satellite communication to mobile users. The satellite includes transponders, each transponder providing linearly polarized signals and at least two orthogonal linear polarized transponders. A plurality of mobile users with a circularly polarized antenna for receiving signals from the satellite, and singly circular or linear polarized transmit antennas for transmitting signals to the satellite. Circuits for providing a correction scheme implemented in a hub side to offset frequency error between two channels produced by the satellite transponder local oscillators mismatch.
