In an SHTF scenario, can GPS units be trusted?

Not unless it is a Dagr. If gps goes encrypted then only these will work.

gps units receive the signals from the gps satellites…they cannot be used to track you down (?)!

The only thing that can happen is that in electronic warfare, the civilian bands get overflooded and wont wont anymore. There is also a side channeled military band that is jamming resistant.

I looked up into it once and it didnt seem to be that hard to get into that band…perhaps…well maybe.

To expand on this, your gps unit receives signals from the satellites and calculates its own position using that information, nothing is sent back.

GPS system is designed to be decreased in accuracy or even shut off on demand for war situation but the amount of civilian Infra that relies on it means they won't do this unless things get really bad.

A little more insight into GPS. In the 90s Clinton removed the protective functionality that narrowed your positioning. It went from 100 feet fuzzy positioning to 10 feet fine positioning. The mechanism had been in place to protect your privacy.
