- The GPS device (phone) just receives information it does not send anything. Multiple satellites are required to get an accurate location. So the device can work out where it is, but no one else will know unless the device is set up to specifically sends that information somewhere.

- The same idea can be used with Mobile base stations, the phone actually connects to all the base stations in range and it has a measure of approximately how far they are away based on signal strength. This can be used to determine approximately where the phone is. The phone must identify itself to each of the base stations. In this way the mobile operator has this information.
