Abstract
A wireless communication system includes multiple wireless communication platforms carrying reflectors for providing spot beams. By using multiple platforms, the payload can be split. Each platform carries only a part of the reflectors needed to provide coverage for a certain geographic area. That allows the reflectors to be of larger size providing smaller spot beams. The multiple platforms of the wireless communication system are designed to be interchangeable. Therefore, only one standby platform is necessary for backup. By further providing an closed-loop pointing control method it is possible to keep multiple platforms pointed accurately relative to each other and relative to the user coverage area.
