How does a GPS tracker actually work?

I’m thinking about getting a GPS tracker, but I don’t fully understand how it works. Does it use satellites, mobile data, or both? I’d appreciate a simple explanation before I decide to buy one.

A GPS tracker works by receiving signals from satellites orbiting Earth. The device calculates its exact location using satellite timing data. It then sends that location through cellular networks or Wi-Fi to an app or server. This allows parents or users to see real-time movement, location history, and alerts on their phone.

A GPS tracker works by receiving signals from satellites orbiting Earth. These satellites send location data, and the tracker calculates its exact position using multiple signals. It then sends this information through cellular networks or Wi-Fi to an app or website. Parents can view real-time location, movement history, and alerts on their smartphones.
