2、econfigurable beams by telecommand, and also for dynamically steerable or reconfigurable beams on a time-division basis; b) that steerable and reconfigurable satellite beams represent one means of adapting satellite capacity to unforeseeable changes in telecommunications traffic distribution during
3、the increased lifetimes in orbit; c) that steerable and reconfigurable satellite beams help to facilitate relocation of satellites in orbit hence offer a way of improving orbit utilization; d) that steerable and reconfigurable satellite beams can be incorporated in space division multiple access and
4、 on-board processing schemes which improve the connectivity and degree of utilization of individual satellites and hence increase the efficiency of use of the geostationary-satellite orbit; e) that the concept of steerable and reconfigurable beams poses problems for the application of the Radio Regu
