This site was created by John Wiseman (@lemonodor) in July 2022.

The map uses data provided by airplanes.live and ADS-B Exchange to generate maps of likely GPS interference, based on aircraft reports of their navigation system accuracy.

If you would like to support my efforts to create sites like this one that make interesting information accessible, then donate. You may also want to consider supporting airplanes.live, a community-run network of receivers—if you have one, or are thinking about it, you can feed them your data.
