How GPS tracking works.

A GPS receiver estimates its position using signals from satellites. Many devices also support other satellite constellations. Obtaining a position and sending it to an app are separate steps: a remote tracker generally needs another connection to deliver the location.

What to check

That delivery may use a mobile network or a supported low-power network. The app displays updates from the service, so coverage, update interval and battery settings influence what you see. Indoors, a device may use additional positioning methods with different accuracy.

Before you rely on it

A Bluetooth-network tag works differently: nearby compatible devices report its location through a shared network. Always check the timestamp on a map. Faster updates usually cost battery energy, and a displayed route may omit movement that occurred between recorded points.
