1. A system for monitoring signal quality of signals to be broadcast to a satellite and broadcast in spot beams to a service area outside of a broadcast area comprising:

  • a broadcast site within a predefined broadcast area, the broadcast site transmits the signals to the satellite and the satellite transmits the signals to the service area foreign to the broadcast;

    a network monitoring operations located at the broadcast site for monitoring signal quality of the signals before the signals are transmitted to the satellite;

    at least one remote site in the service area that receives the signals broadcast by the satellite;

    wherein said at least one remote site in the foreign service area further comprises a signal strength meter for measuring a strength of the signals, the signal strength measurement being used to detect problems with the satellite transmission to the foreign service area;

    wherein the network monitoring operations further comprises a computer for monitoring the signal strength measurements;

    wherein said computer has software for analyzing the signal strength measurements and raising an alarm upon loss or degradation of the signals;

    means for avoiding alarms for signal degradation that is a result of rain fade;

    a database for storing signal strength measurements from said at least one remote site thereby providing a history of satellite transponder performance;

    database being used to support long term trend analysis of the satellite transponder;

    wherein said signal strength meter measures the signal strength of the CONUS transponder carrier signals.
