Your phone is continuously tracking these signals to get an estimate of your location even when you are offline. Does phone GPS work when phone is off?A phone that is turned off is difficult to track because it stops sending signals to cell towers. However, the service provider or internet provider can show the last location once it's switched back on.

The military uses dual-frequency equipment to avoid signal distortions that could jeopardize their mission or research. This type of equipment is not exclusive for government use, though. What is GNSS technology?Global navigation satellite system (GNSS) is a general term describing any satellite constellation that provides positioning, navigation, and timing (PNT) services on a global or regional basis.
