if geolocation data can be captured in the same signature, that would be a good enough approximation for most relevant cases I think.

- brainwad 28d agoGNSS signals can be relatively easily faked because the original signals are very weak so overpowering them doesn't require much broadcast power.
- ares623 28d agoah, damn.
- 15155 28d agoJamming them is easy, replaying them so as to trick unacquainted receivers is easy, but "faking" a network of signals so as to precisely control present a specific location is not easy or feasible. "Overpowering" (as to jam) inherently means detectable, these signals are arriving below the noise floor anyway. And if you aren't overpowering, the original signals will leak through. Also, depending on the sophistication of the receiver, your ability to present an implausibly different location may not exist at all (AGPS.)
- brainwad 27d agoIt seems feasible for state actors, at least: https://en.wikipedia.org/wiki/GNSS_spoofing#Ocurrences https://en.wikipedia.org/wiki/GNSS_spoofing#Ocurrences
- 15155 27d agoYes, a motivated actor can move a naive receiver somewhere different than where it thinks it is by some small amount - ideally outside of the CEP of whatever weapons system is targeting, but that's much different than precisely controlling the location to be somewhere else arbitrarily.
