    摘要： A method for detection of an Equivalent Isotropically Radiated Power (EIRP) degradation of a radio frequency (RF) transmitter of a satellite being in an orbit with a repeating ground track is provided. The method comprises obtaining sets of signal-to-noise (C/N 0 ) data from a first source and obtaining satellite orbit data of the satellite from a second source. Each set of C/N 0 data is associated with the satellite and a respective one of a plurality of receivers. The method further comprises computingtemporal information on an elevational and azimuthal direction of the satellite with respect to respective locations of each of the plurality of receivers based on the satellite orbit data and the respective locations of each of the plurality of receivers. The method further comprises determining a time interval based on the temporal information. The repeating ground track repeats a single time in the time interval. The method further comprises determining, for each of the plurality of receivers, a respective one of a first plurality of differences between a first value of the respective set of C/N 0 data corresponding to a first time point and a second value of the respective set of C/N 0 data corresponding to a second time point. The first and second time points are apart by the time interval. The method further comprises computing a first average of the first plurality of differences. The method further comprises comparing the computed first average with a predetermined threshold. The method further comprises triggering a signal, when the computed first average is larger than the predetermined threshold. The signal indicates detection of the EIRP degradation of the transmitter. Further a monitoring device for detection of an Equivalent Isotropically Radiated Power (EIRP) degradation of a radio frequency (RF) transmitter of a satellite is provided.
