Have you tried risk management instead? You can turn off your cellular network, wifi network, and Bluetooth. Hell, you can just toggle on air plane mode. This should theoretically turn off GPS too.
If this isn’t enough management then you’re suspecting that the OS is somehow keeping track of you or there’s some firmware that is bypassing OS controls to track you. Unless you are doing something highly illegal or you are someone highly important, I highly doubt this is the case.
I do not think I need to be important at all. I just want something to throw it in. I have also checked a degoogled ohone that I think might actually work in my country.
Last I checked airplane mode does not disable GPS as it is a passive service. The phone will track your movement and then send it all next time you connect.
You must know something I don’t.
AFAIK, GPS works by fetching signals from satellites.
If you disable your Bluetooth/wifi antenna, you won’t know your relative location to other devices. If you disable your cellular antenna, you won’t know your relative location to cell towers. I presume that you would need some of that data to know your position relative to satellites but maybe I’m missing something. Maybe it receives data from satellites directly?
Yes, GPS works by measuring your distance from several GPS satellites (based on the timing of the signals they send). If a few distances are known, it narrows it down to a point (the satellite orbits are known so you know where they are at any time).
I've owned several stand-alone GPS receivers before phones started to include the feature.
You can download offline maps to phones so that you can navigate without any phone signal.
