- dogma1138 10y agoGalileo isn't in LEO https://en.wikipedia.org/wiki/Medium_Earth_orbit https://en.wikipedia.org/wiki/Medium_Earth_orbit but yes, shutting off the signal would mean that a radius of about 7000 (GPS sats can be seen across about 6500~ miles depending on the exact orbit and angle, Galileo will have more coverage since they are at a higher orbit, if you really want to know here is how you calculate it http://gis.stackexchange.com/questions/77651/how-to-find-ring-of-coverage-of-gps-satellite-on-wgs-84-ellipsoid http://gis.stackexchange.com/questions/77651/how-to-find-rin...) miles has no SatNav... Jamming can shut down GPS in any range from 10M to 100,000M turning the transmitters of effectively shuts down GPS to half the globe. ]
