Problem signature terminal diagnosis method and system
View Patent ↗Systems and methods for problem signature terminal diagnosis are disclosed. In an example embodiment, measured operational statistics of a satellite terminal of a peer group of satellite terminals are received and converted into normalized operation statistics. Normalized deviations of the operational statistics are determined and compared to the threshold deviations. A diagnosis zone corresponding to a problem signature is determined based on the normalized deviations by determining that coordinates of the normalized deviations are within the diagnosis zone, comparing a ratio based on the normalized deviations to a threshold ratio, or comparing a differential of the normalized deviations to a threshold differential. A satellite terminal is diagnosed with a problem defined by the problem signature based on the determined diagnosis zone.
