Real-time signal validation method and system
View Patent ↗Systems and methods for real-time signal validation are disclosed. In an example embodiment, a subset of terminals in a peer group of satellite terminals is determined. Operational statistics of the satellite terminals in the subset of terminals is measured. Operational statistics of each of the satellite terminals in the subset of terminals is compared to a prior measurement of the same operational statistics. An offset between a current measurement of the operational statistics and the prior measurement of the same operational statistics is determined. An average offset of the current measurement of the operational statistics and the prior measurement of the same operational statistics is determined for the subset of terminals. The average offset for the subset of terminals is merged with a previously determined peer group operational statistic. A signal validation of a terminal is performed using an updated deviation value.

16. The method of claim 1 , wherein updating the previously determined peer group operational statistic includes:
comparing a first measurement of the operational statistic of each of the satellite terminals in the subset of terminals to a prior second measurement of the same operational statistic for each of the satellite terminals in the subset of terminals; and
determining an offset between the first measurement of the operational statistic and the prior second measurement of the same operational statistic for each of the satellite terminals in the subset of terminals.
17. The method of claim 16 , wherein updating the previously determined peer group operational statistic further includes:
determining an average offset of the first measurement of the operational statistic and the prior second measurement of the same operational statistic for the subset of terminals; and
