Selective availability is obsolete due to the existence of Glonass, Galileo and Beideu. But if you’re in a GPS denied area due to jamming or spoofing, you need backup systems ready to go.

Interesting. So there isn't a chance that the government might disable it in some fashion? Surprising that there isn't a provision for this. Similar with the Internet — in a time of “emergency” there would be a provision to shut it down. Selectively or completely. Call me a conspiracy nut.

Selective availability still provided reasonable accuracy, too if some kind of weapon were to be used or targeting system were to be used.
