Geolocation & GPS Accuracy Guide

How to Use This Tool

  1. Click "Locate GPS Position" and select "Allow" when your browser requests location permissions.
  2. View your active location pinpointed on the OpenStreetMap interactive view.
  3. Check the Accuracy Radius: smaller values (e.g. 5–15 meters) mean a tighter satellite or Wi-Fi lock.
  4. Inspect the coordinates table for Decimal Degrees (DD) and Degrees Minutes Seconds (DMS) formats.

How Desktop Browsers Estimate Location Without GPS

While smartphones have true satellite GPS receiver chips, most laptops and desktop PCs do not. Instead, browsers use Wi-Fi BSSID Positioning: the browser scans the signal strength of nearby Wi-Fi router MAC addresses and cross-references them against geolocation databases, achieving accuracy within 20–50 meters without satellites.

Why Your Location Might Point to Another City

If you connect to the internet through an Ethernet cable with Wi-Fi disabled, the browser must fall back to IP Geolocation. Because public IP addresses are registered to internet service provider (ISP) switching hubs, your location may appear several miles away or in your regional ISP headquarters.

VPNs & Privacy Protection

If you are connected to a Virtual Private Network (VPN), your IP traffic exits through a remote server. The browser will place your location at the VPN data center's city rather than your physical home. All geolocation checks run locally on your device and are never stored on our servers.
