Click 'Start Test' to get your current location. Your position data stays in your browser.
Allow location access when prompted by your browser. GPS accuracy varies by device.
Altitude and speed data may not be available on all devices, especially desktops.
Your location data is processed entirely in the browser and never sent to any server.
Devices determine location using multiple methods: GPS (Global Positioning System) uses signals from 24+ satellites to calculate position with 3-5 meter accuracy. Wi-Fi positioning compares nearby access points against a database — accuracy of 15-40 meters. Cell tower triangulation uses mobile network signals — accuracy of 100-300 meters. Devices typically combine all available methods for the best result.
Location accuracy varies significantly. Outdoors with clear sky provides the best GPS accuracy (3-5m). Urban areas may experience multipath errors from signal reflections off buildings. Indoors, GPS may be unavailable, falling back to Wi-Fi positioning (15-40m). Altitude readings from GPS are typically less accurate than horizontal position — expect ±10-30 meters.
The Geolocation API always requires explicit user permission — browsers show a prominent permission dialog. Location data is never automatically shared. The API supports two modes: getCurrentPosition for one-time readings and watchPosition for continuous tracking. The enableHighAccuracy option requests GPS when available (uses more battery) vs. Wi-Fi/cell positioning.
Large accuracy values usually mean GPS is unavailable and the device is using Wi-Fi or cell tower positioning. This commonly happens indoors. Go outside with a clear sky view and wait 30-60 seconds for GPS to acquire satellites for better accuracy.
No. Location coordinates are only displayed in your browser and never sent to any server. The Geolocation API processes everything client-side. You can revoke location permission at any time through your browser settings.
Speed detection requires GPS and works best at moderate-to-high speeds (walking, driving). Very slow movements may not register. Some devices only report speed when using GPS, not Wi-Fi positioning. Try testing outdoors while walking.
