Method of using feedback from consumer terminals to adaptively control a satellite system
View Patent ↗A system and a methodology uses data provided from consumer terminals in a satellite system to reconfigure a satellite to thereby optimize the strength of signals transmitted by the satellite. The data from the consumer terminals may be used to provide diagnostic information about the reception of signals at various points in an area covered by a satellite broadcasting system and to compensate for attenuation of signals transmitted by the satellite due to weather storms, or other atmospheric conditions. Such use of consumer terminals eliminates the need to place expensive monitoring stations throughout an area covered by a satellite broadcasting system, resulting in substantial reduction in overall system cost. Additionally, given the widespread distribution of consumer terminals, greater monitoring coverage is achieved than with a limited number of monitoring stations.
1. A method of controlling a satellite comprising:
broadcasting a satellite signal;
receiving the satellite signal at a number of user terminals;
detecting the signal strength of the satellite signal at each of the user terminals;
transmitting a second signal from each of the number of user terminals to a satellite control station, the second signal corresponding to the signal strength of the satellite signal received at each of the number of user terminals; and
adjusting an operative characteristic of the satellite in response to one or more of the second signals, comprising the steps of:
acquiring the second signals from each of the number of user terminals;
mapping each of the second signals to a grid;
converting the second signals to link margin values on the grid;
applying a pattern recognition to the link margin values on the grid to detect signal degradation values;
predicting weather;
predicting link margin values on the grid from the signal degradation values and the predicted weather; and
adjusting the operative characteristic of the satellite using the predicted future link margin values.

4. The method of claim 1 wherein the operative characteristic of the satellite adjusted in response to one or more of the second signals is a transponder gain setting.
5. The method of claim 1 wherein the operative characteristic of the satellite adjusted in response to one or more of the second signals is a directional setting of the satellite.
6. The method of claim 1 wherein the operative characteristic of the satellite adjusted in response to one or more of the second signals is a downlink antenna gain pattern.
