Abstract:
1. A method of evaluating a bent-pipe repeater path, comprising the steps of: identifying parameters of a transmitting earth station and a receiving earth station including the noise temperature of the transmitting and receiving earth station and the noise temperature of space; identifying component performance parameters including the gain, loss, and noise temperature of all of the repeater components in the bent-pipe repeater path; predicting, using a processor including a non-transitory memory device in an evaluation system prior to building a physical model of a bent pipe repeater, repeater performance of the bent-pipe repeater path as a function of the parameters of the transmitting and receiving earth stations and the component performance parameters of the gain, loss, and noise temperature of all of the repeater components; predicting a relative saturation of an amplifier in the bent-pipe repeater path when the amplifier is in an unpowered state, the relative saturation comprising an input power level of the bent-pipe repeater path relative to a saturation point of the repeater component; communicating, on a graphical user interface (GUI), the component performance parameters including the gain, loss, and noise temperature of all of the repeater components, the parameters of the transmitting and receiving earth station, and the predicted repeater performance; and adjusting the gain, loss, and noise temperature of all of the component performance parameters to manage the predicted repeater performance to be within a predetermined range of desired repeater performance.
