Abstract
A method is presented to extend a frequency lock range of a received RF signal in a satellite receiver. One step in the method includes analyzing data information of a preamble associated with the received satellite RF signal. Another step includes determining an estimated frequency value that is a function of the analyzed data information that further includes at least a portion of the frequency error formed therein. A further step includes comparing the determined estimated frequency value to a predetermined threshold value. Another step includes using the determined estimated frequency value when the determined frequency value is greater than the predetermined threshold value to operatively control tracking mode electronic circuitry disposed in the satellite receiver to attain frequency lock on the received satellite RF signal.
