Abstract: A method of determining parameters for the design of ground equipment for satellite link systems using duplex links is disclosed. The method has particular application to determining transponder power requirements and antenna size. The method comprises selecting required availability of the satellite system and ground sites for the equipment and determining site degradation parameters for the ground sites. A range where no up link power control is required is also determined and a point of minimum transponder power is determined to enable the parameters to be selected.
