Abstract
Methods and systems for acquiring service for a user terminal with a satellite communications system are provided wherein geographic information is received via an electromagnetic transmission at the user terminal defining a location of the user terminal. A control channel is selected corresponding to one of the spot beams covering the location of the user terminal using the geographic information. The user terminal acquires service from the satellite communications system over the control channel. The geographic information enables the user terminal to shorten the search time by searching those channels which correspond to the geographic region determined from the geographic information.
