This is interesting >The 2024 GPS Testing for Critical Infrastructure (GET-CI) event is set for the fall of 2024. >This event provides an opportunity for CI O&O and manufacturers of commercial GPS receivers used in critical infrastructure to perform equipment evaluations in a rarely available live-sky spoofing and jamming environment. For the 2024 GET-CI event, S&T will create a live-sky GPS environment primarily for fixed infrastructure applications but will also support some ground-based mobile applications.

> 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.

I remember something like this from 2011: https://web.archive.org/web/20111015232120/http://navcen.uscg.gov/pdf/lnms/lnm07032011.pdf#page=4 https://web.archive.org/web/20111015232120/http://navcen.usc... “SOUTHEAST ATLANTIC COAST: GPS Testing Information THE GPS NAVIGATION SIGNALS MAY BE UNRELIABLE FROM 20 JAN 2011 - 22 FEB 2011 FROM 0000Z - 0245Z DUE TO TESTING ON GPS FREQUENCIES USED IN SHIPBOARD NAVIGATION AND HANDHELD SYSTEMS. GPS SYSTEMS THAT RELY ON GPS, SUCH AS E-911, AIS AND DSC, MAY BE AFFECTED WITHIN A 150 NM RADIUS OF POSITION 30 49.09N 80 28.18W.
