Test de coordonnées GPS
Demandez votre position avec une action explicite, inspectez la précision et l'altitude et copiez les coordonnées sans les stocker.
Interface de test
Votre navigateur peut demander l'autorisation après avoir appuyé sur Démarrer.La précision est une estimation rapportée par l'appareil. Un plus petit nombre est préférable ; les lectures intérieures sont souvent beaucoup moins précises.
Comment utiliser cet outil
- Click Get my location and choose Allow in the browser prompt.
- Wait for the first position and read latitude, longitude, accuracy, and time.
- Use Watch location for repeated readings and observe accuracy changes.
- Copy coordinates or open a map link explicitly if desired, then stop watching.

Explication technique
The Geolocation API uses GPS, Wi-Fi, cellular, or IP-derived positioning depending on the device and operating system. accuracy is a radius in metres reported by the provider, not a guarantee of correctness.
Indoor readings can be poor. Altitude is only available when the provider supplies it and may be unreliable. The browser may return a cached position; the time-to-first-fix shown here is the page’s request time, not a hardware warm-start measurement.
Dépannage
Location permission is denied
Reset the location permission for this site in the browser settings and try again.
Position is inaccurate
Move outdoors, wait for more satellites, and avoid using a VPN for network-based positioning.
No position is returned
Some desktops lack location providers. Check operating-system location services.
Requests time out
Try again in an area with better signal and keep the page in the foreground.
