A common misconception is that GPS requires an internet connection to function. In reality, GPS works independently of the internet by relying on satellite signals.
Satellite-Based Functioning
GPS receivers calculate location by receiving signals from satellites orbiting the Earth. These signals contain precise timing and orbital information, allowing the receiver to determine its position without any internet access.
Role of the Internet
The internet is not required for GPS positioning, but it enhances functionality. Online maps, traffic updates, and Assisted GPS (A-GPS) use data connections to improve speed and user experience.
Offline GPS Usage
GPS devices can function offline if maps are pre-downloaded. Many navigation apps allow offline map access for this reason.
GPS Trackers Without Internet
Dedicated GPS trackers store location data internally or transmit it later when a cellular connection is available.
Conclusion
GPS works perfectly without the internet for location detection. Internet connectivity only improves map loading, speed, and additional features.
