Fabulously complicated and only producible with exotic emitters, sensors, and high frequency ICs. Probably as easily jammed or forced into calibration state with a directed low frequency em pulse generator. High tech garbage. We will not fare any better than Ukraine relying on tech like this.
Fortunately someone recently posted a real technological wonder - the F-14 cpu, old timers were messing with multithreaded compute while I was muddling along learning pong line by line from a hobbyist magazine.

Probably right. But,

Ukraine is faring amazing well, aren’t they?
Russia controls a fraction of the territory, has suffered a million casualties, and lost many many armored vehicles and combat aircraft.

I remember reading something about defunding some satellites, so I went looking. All I could find is articles about the US not providing backup satellites.

Its about countering adversarial GPS spoofing, not a lack of satellites.

And we can't trust the Pentago anymore, so the circle is completed (see the recent "Ukraine deal" which is basically just a sell-out toward the USA allying with Russia).
