Abstract
A method and system for aligning an antenna reflector with satellites in a satellite configuration. A method in accordance with the present invention comprises pointing the reflector to an orbital slot used in the satellite configuration, wherein only one satellite in the orbital slot transmits first circularly polarized signals, and adjusting the reflector to maximize reception of the first circularly polarized signals from the orbital slot. A system in accordance with the present invention comprises a reflector, a power meter coupled to the reflector, wherein the power meter and reflector are tuned to receive first circularly polarized signals, and an alignment mechanism, coupled to the reflector, wherein the alignment mechanism is manipulated to point the reflector at an orbital slot wherein only one satellite in the orbital slot transmits the first circularly polarized signals, and to adjust the reflector to maximize reception of the first circularly polarized signals from the orbital slot.
