It would be impossible to have regional GPS outages if the GPS system were satellite based.
This is evidence that GPS is ground based. It is merely an extension of an earlier technology (WWII) named LORAN.
You can test this by driving south into Mexico from California. You GPS signal will diminish and disappear as you drive south.
You can totally have regional outage with a satellite based system. They’re jamming, jammers have a range, which makes it regional.
It's military signal jamming. Of course it could be regional.
Uh...no. The interference sources are ground based. All one has to do is create enough noise in the GPS frequency band that the GPS satellite based signals are masked. It does take a considerable amount of noise since GPS signals and receivers are designed to be distinguishable with noise, but at some point the receiver can no longer track the signal.

One of the dumbest posts ever.
I’ve noticed over the last few years there’s been a re-emergence of flat earth theory, which among many things, states that satellites are impossible and fake, because they cannot escape earth’s firmament.
Is that what your comment is eluding to?
You’re amongst FRiends, come’on. Please ‘splain.
Lots of military and defense contractor engineers here want to know how fooled they’ve / we’ve been ‘bout satellites, space n stuff... ;n)

Wow, you need to adjust your tin-foil hat.
The GPS system is satellite-based, although there are ground-based augmentation systems that essentially broadcast a correction: the ground station is at a known position, and broadcasts the difference between the known position and the position measured via GPS. GPS receivers apply this correction and display a more accurate position. It's known as D-GPS, or differential GPS.
GPS satellite transmissions are very weak, just above the noise floor. So, it takes a sophisticated receiver with lots of signal processing to lock on to it. As a result, a ground transmitter can easily interfere by simply broadcasting noise on the GPS downlink frequencies. A stronger signal will interfere over a wider area.
Also, the DoD has the ability to control the satellite constellation over a specific area of the Earth. GPS satellites can degrade the accuracy by introducing random error into the signal, and by doing so for all satellites as they pass over a particular part of the Earth, the GPS constellation becomes less useful or even useless in that area.
The DoD has done this over war zones where they may or may not be operating. But, military GPS receivers are not affected, because they use a separate encrypted signal.
I’ve used GPS in Mexico.
