Patent ID: 7675462

Claim:
A method for an alignment of an earth station antenna with a satellite antenna of a satellite, comprising: initiating an alignment request for an earth station by emitting a reference signal at a predetermined identification frequency range by an antenna of the earth station to a satellite antenna of a satellite; scanning the identification frequency range by an antenna misalignment monitoring station (AMMS) in communication with the satellite to detect and decode the reference signal, wherein the reference signal is used as a carrier for authentication information about the earth station; authenticating the earth station to enable communication between the AMMS and the earth station via the satellite through a forward link; after authentication, commanding the earth station by the AMMS via the forward link to transmit the reference signal at a dedicated frequency outside the identification frequency range for communicating antenna misalignment information; and receiving by earth station from the AMMS antenna misalignment information for alignment of the earth station antenna with the satellite antenna.
