1. A method of determining parameters for the design of ground equipment for a satellite link system utilising duplex links comprising:
- selecting a required availability of the satellite system;
choosing at least first and second ground sites for ground equipment;
determining site degradation parameters for the ground sites;
determining an operating range where no uplink power control is required; and
determining a point of minimum transponder power;
such that parameters of the ground equipment required to transmit the duplex signal can be selected for the design of the ground equipment.

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.
