1. A method comprising: receiving operational statistics of a satellite terminal of a peer group of satellite terminals, the operational statistics including a first measured operational statistic for a first parameter of the satellite terminal and a second measured operational statistic for a second parameter of the satellite terminal; converting the first measured operational statistic into a first normalized operation statistic that is normalized to the peer group; converting the second measured operational statistic into a second normalized operation statistic that is normalized to the peer group; determining a first normalized deviation of the first normalized operational statistics; determining a second normalized deviation of the second normalized operational statistics; comparing the first normalized deviation to at least a first threshold deviation; comparing the second normalized deviation to at least a second threshold deviation; and determining a first diagnosis zone based on the first normalized deviation and the second normalized deviation, the first diagnosis zone corresponding to a problem signature, wherein determining the first diagnosis zone includes at least one of: (i) determining that coordinates of the first normalized deviation and the second normalized deviation are within the first diagnosis zone; (ii) comparing a ratio based on the first normalized deviation and the second normalized deviation to a threshold ratio; and (iii) comparing a differential of the first normalized deviation and the second normalized deviation to a threshold differential; and diagnosing the satellite terminal with a problem defined by the problem signature based on the determined first diagnosis zone.
