GPS Tracking Without Internet
Answer: GPS tracking can work without internet because location comes from satellites. You still need battery power, adequate sky view, and preferably offline maps so the track is meaningful on terrain.
How it works
Cellular networks help with assisted GPS startup and online services, but they are not the source of GPS ranging. Once a fix is available, apps can log coordinates offline.
Practical considerations
Background recording policies vary by OS. Keep the app permitted for location, watch battery in cold weather, and verify the track after short test walks before a long expedition.
