Owen, GPS does come from above but it is a very weak signal compared to the jamming systems. The jammers totally screw up the frequencies used by the GPS.

I had a guaranteed military sale with ED 209 - renovation program, spare parts for twenty-five years... Who cares if it worked or not?

It's even that way fishing for tuna. I had to install voice scramblers to cover conversations between boat, base station and other boats. The conversation was obscured, so the next step was homing in on the RF. Many boats had radio direction finders. Many had scanners. The problem was identifying what frequency to set the RDF to point at the origin of the VHF transmission. I resolved that by integrating a Taiyo RDF with a Regency scanner. I tapped the goniometer output and routed into the Regency scanner front end. I tapped the 10.7 MHz IF of the scanner and routed it back inside of the RDF ahead of the detector circuits. Voila! The scanner stopped on an active frequency and the RDF pointed at the origin. My employer sold the conversion to every boat in the harbor. $10 in parts and 30 minutes of labor.
It was a perpetual technical counter measure effort even when just fishing for tuna. The stakes are much higher on the battlefield and it pays better.
GPS is very easy to jam. I’m an airline pilot and I see it quite a bit.
Reminds me of a quote about WWIII, that no matter who ‘wins’, the war after that will be fought with sticks and stones.
I have some ideas, if the right people are interested.
All your assumptions about GPS are dead wrong.
Probably best I not waste time on explaining the difficulty of jamming or spoofing GPS.
Learn what decibel loss can be expected if a signal source is below the hemispheric receive pattern.
Learn about spread spectrum.
Learn about Kalman filter weighting in a navigation solution with multiple sensors.
Learn about C/A, P, and Y code, and why it largely won’t matter since the Russians have their Glonass, the Chinese their own Beisomething, the EU its own, India, Japan . . . all have navigation satellite constellations.
In a general sense, if artillery guidance is failing, it is not GPS obfuscation that is doing it. It is standard practice for KFs to unweight GPS in a nav solution.
The Russians have another technology doing this. Far superior to ours, as usual.
WW2 level tech would not be affected by emp. Tube gear is not affected. Pls point/coil cars not affected. Wars would still go on. As always.
