GPS Coordinates Test

Request your location with an explicit action, inspect accuracy and altitude, and copy coordinates without storing them.

Privacy: Coordinates are processed in this browser tab. They are not sent to a server or saved by this site. Map links open only when you choose them.

Accuracy is an estimate reported by the device. A smaller number is better; indoor readings are often much less accurate.

Location is sensitive. This page processes coordinates in your browser and does not send them to the server. The map is loaded from OpenStreetMap only when you ask for it.

How to use this tool

  1. Click Get my location and choose Allow in the browser prompt.
  2. Wait for the first position and read latitude, longitude, accuracy, and time.
  3. Use Watch location for repeated readings and observe accuracy changes.
  4. Copy coordinates or open a map link explicitly if desired, then stop watching.

Technical explanation

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.

Troubleshooting

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.
