SATELLITE PERFORMANCE MONITORING
First Claim
1. A method for monitoring the performance of a satellite communication system comprising:
- measuring, at a gateway terminal, a total receive power of a signal received from a satellite under normal operating conditions;
measuring one of a signal only power and a signal to noise plus interference ratio (SINR) for a signal received from the satellite under normal operating conditions;
measuring a total thermal noise component of the signal received from the satellite;
measuring a downlink thermal noise component of the signal received from the satellite; and
calculating satellite communication system operating parameters using the total receive power, the signal only power or the SINR, the total thermal noise component, and the downlink thermal noise component measurements.

Abstract
Techniques for monitoring transmission performance of a satellite communications systems are provided, including techniques for measuring the primary contributors to the end-to-end SNR, including the uplink SNR, the downlink SNR, and the C/I for each link in the network. These individual measurements are used to estimate satellite effective isotropic radiated power (EIRP), satellite antenna gain-to-noise-temperature (G/T), and loss due to an Earth Terminal pointing error. The EIRP, satellite antenna G/T and loss due to Earth terminal pointing error may then be used to determine operating parameters for the satellite communications network that enable the network to operate more efficiently.
