Systems and methods for network performance monitoring
A communications system may include user equipment (UE) devices, communications satellites, gateways, a satellite communications (satcom) network, and network performance monitoring devices. The monitoring devices may generate forward link signal information associated with forward link signals received from the satellites and may generate reverse link packets transmitted to the gateways via the satellites. The monitoring devices and the gateways may generate reverse link signal information associated with the reverse link packets. The satcom network may identify differences between the first and second reverse link signal information or between the forward link signal information and predicted forward link signal information for the monitoring devices. When the differences exceed a threshold value, the satcom network may generate and transmit error information used to diagnose, debug, and/or repair the potential errors in the constellation or gateways.
