gnss-gateway: navigation when GPS disappears
An Android app that estimates position from vehicle speed, a gyroscope, and road data when GPS is jammed or spoofed, then feeds that position to the navigation app already in use.
- For
- Android drivers and cyclists navigating through unreliable GPS
- Worth noticing
- With an OBD adapter, a car setup can start a navigation session when the engine starts and end it roughly two minutes after shutdown.
Field notes
The setup guidance calls for Android 8.0 or newer with Google Play services, a steady phone mount, and either an OBD-II adapter for a car or a speed sensor for a bicycle. In a car, the adapter can trigger a session at engine start; the page says the session ends roughly two minutes after shutdown when the vehicle is stationary. It also explains that the app returns to satellite positioning when the signal again matches movement.
