Abstract:
A geolocation method and system for locating the source of interference to a high throughput satellite. The method involves determining relative power level differences between interference signals received by the victim spot beam and co-colored nearby spot beams on the same satellite. Using beam pattern data, the relative power levels for a pair of beams determines contour lines of possible location the correspond to the relative power difference in the signals received by the two beams in the pair. A point of intersection of contour lines from multiple pairs of spot beams indicates the location of the source of interference.

Claim (Index 1):
A satellite system to locate an uplink interference source, the system comprising:\n a plurality of co-coloured spot beam antennas to receive uplink signals and with each spot beam having a respective geographic coverage area, the respective coverage areas of the co-coloured spot beam antennas being arranged in a grid of non-overlapping areas in a color re-use pattern; a digital channelizing processor to digitally channelize received signals from each co-coloured spot beam antennas to produce respective digitized spectrum; a spectrum analysis module to identify an interference carrier in one of the digitized spectrums and to determine relative power levels between the interference carrier in said one of the digitized spectrums and a lower power interference carrier at a same frequency in two or more of the other respective digitized spectrums; and a geolocation module to, for each of the relative power levels, determine contour lines of geographic location based on that relative power level, and to identify a geographical location of the uplink interference source based on an intersection between two or more of the contour lines.
