The Uplink Power Control System (UPC) is a selfcontained, rack-mountable unit, designed for geostationary satellite communication systems. It adjusts the strength of uplink signals at IF frequencies to compensate for varying weather conditions. The UPC can be setup completely from the front panel or over a remote bus via a host computer. All monitor and control functions are accessible at the front panel as well as over the remote bus.
A Beacon Receiver must provide the UPC with a DC voltage proportional to the downlink signal strength.
The Uplink Power Control Unit is equipped with fully redundant power supplies.
