In a redacted acquisition document obtained by the tech news site 404 Media, the immigration agency proposes entering into a contract to buy “all-in-one” tools from a company called PenLink that will allow agents to “compile, process, and validate billions of daily location signals from hundreds of millions of mobile devices.” The document also mentions payments for services involving “face detection,” “advanced face search,” and a “dark web data feed.”

Isn't GPS only one way? Is the phone then sending the data to the carrier?

    I'm a bit confused by your question...GPS definitely requires communication between your phone and a satellite (i.e. can't track you if your GPS unit is off - maybe you're thinking of satellite imaging?). EDIT: This is actually incorrect, see comments below

    With wifi calling, yes, data is being sent to the carrier, but not via a signal that can be triangulated, so the most accurate location data they can gather is your IP address, which a VPN can easily hide.

    Or do you mean in terms of generalized location tracking? In which case yes, highly accurate location data is shared by your phone with your carrier by default, just by way of how cellular networks function; no GPS required.

    My understanding of GPS is your phone uses satellite positions to figure out it's location. The satellites are not receiving info from your phone/Garmin.

    I think the problem is that once your phone knows its location from GPS, google and apps can access this data. The data is then shared with advertisers and also, you know, government agencies.

    Unfortunately, even just the names of nearby WiFi networks and Bluetooth connections can be used to determine location. If apps and google services have access to this info, they still have location data on you, even with your cell and GPS radios disabled.

    Supposedly GOS doesn't allow google or apps to access the location data unless you allow it, which is nice.
