A few months ago I learned that there were only around 30 GPS satellites serving the entire planet.
I suspect that is all the GNSS you know of.

Well, truth to be told: When I bought my current mobile in early spring 2016, using it properly for positioning would have been against the law in USA: For another two years, receiving positioning information from Galileo satellites was considered 'communicating with a foreign satellite system', which was not permitted until November 2018. I have not seen similar information for GLONASS, but would be surprised if communicating with Russian satellites were more acceptable than communicating with European ones. Even more so for the BeiDou system from China (which we call Red China).

Any decent smartphone sold in Europe for the last few years can handle both GPS, Galileo, GLONASS and BeiDou. My 2016 vintage S7 only handles the first two of these. At the moment, the two have 14 satellites over my head. I guess doubling the number of GNSS services would roughly double the number of satellites over my head as well. Wikipedia tells me that until Nov. 2018, S7 phones sold in the US had Galileo blocked, and needed a software update when listening to them became legal.

Fact is, if the entire GPS network was bombed, all 30 satellites at the same time, it would take a long time before non-US smartphone users (and users of dedicated GNSS equipment) would notice. With the old US panic for 'communicating with foreign satellite systems', I wonder what would be the result in USA. Would a total breakdown of GPS paralyze a lot of activities, because Usatians are so patriotic that they will not communicate with foreign satellites? Or maybe reject Galileo, GLONASS and BeiDou on NIH grounds?

Or would most Usatian people and systems be as unaffected by a GPS breakdown as European customers? In particular (but I do not expect any reliable answer to this!), has the USAF degraded themselves to install duplicate (triplicate, quadruplicate) NIH GNSS solutions in their various systems, in case GPS is sabotaged?

Religious freedom is the freedom to say that two plus two make five.
