Abstract
A method for acquiring a spotbeam beacon frequency is disclosed. The method comprises a fast synchronization procedure wherein the beacon frequency of the spotbeam is first acquired using a carrier acquisition process. A coarse time acquisition procedure is then performed on the acquired beacon frequency followed by a performance of a fine time and frequency acquisition process. The entire process enables spotbeam beacon acquisition in a range of approximately 2.7-27 seconds.
