GPS signals are really weak by the time they get all the way down to earth from 23,000 km away. A few watts worth of jamming is all it takes to block civilian signals for hundreds of miles around in line of sight of that jammer. Put the jammer on an aircraft and you can jam country sized well European country sized area’s with ease. The gen3 US GPS have the M code that is specifically designed to be higher powered and jam resistant but only our military and NATO has access to it. Airlines use the L5 and L1 plus L2c signals all of which are much lower powered and easy to jam. The USA and the Europeans used to have LORAN C ground based hyperbolic navigation system with million watt transmitters that was nearly impossible to jam over any significant area. It was shutdown under the Big O to save 25 million per year in operating costs and was the only viable back up to GPS plus it made us invulnerable to advisory jamming and now you know why it was cut off it weakened the USA considerably. The Russians have a identical copy of that system translated to seagull since that what the signals sound like in audio. They never turned it off and they are using it right now in Uke because the Ukes are also jamming the Russian GLONASS system which is the copy of our GPS. Before 1990 most commercial airliners had LORAN C navigation and would today if they still had it be immune to GPS jamming. There is a big push to bring back LORAN in a modern form specifically to back up GPS with a million watt signal a few hundred miles away vs 50 watts from 12000+ miles away. The difference is several orders of magnitude in signal strength.
After that b——— Obama had the road signs and especially route signs removed to make us more helpless and dependent on technology I bought and keep a lot of map books in my car
Thanks for all that info!
This is one of the best examples of why I don’t thing WW3 will be as much fun as others here seem to think.
We basically BLIND OURSELVES militarily (without even making the Russians take out our satellites) and then stick our bucks up in the air to tell Putin that we’ll clobber him. And I know we’ve crippled ourselves in many other military areas too.
Great time to start WW3!
