Satellites and signal distribution methods and off-set pattern for sending signals
Abstract:
The invention relates to methods, systems, and satellites that employ an off-set pattern of spot-beams to transmit signals or television signals over a desired area of the earth. In one example, a heavily populated metropolitan area in the continental United States is covered by at least two patterns of spot-beams, where the patterns are off-set to one another by a lateral or translational displacement, rotation, or both. The off-set patterns can be used in conjunction with existing satellites and systems and incorporated into new satellites and systems. The methods reduce problems associated with the straddling of subscriber areas caused by local-into-local requirements, and advantageously allow increased spot-beam capacity, and the reduction in earth uplink stations.
