> perform equipment evaluations in a rarely available live-sky spoofing and jamming environment I'm guessing there are aspects of this prepared interference that are unique. We've had a number of planned & unexplained outages/jammings in the US. I recall a planned one shaped like an inverted cone, with the impact broader area at higher altitudes. I was able to math the cone-point, somewhere out west and at a low alt. Diff sites track them. ref: https://gpsjam.org/ https://gpsjam.org/ ref: https://www.navcen.uscg.gov/gps-problem-report-status https://www.navcen.uscg.gov/gps-problem-report-status
