ACOUSTIC GEOLOCATION

Find the flights.
Test the location.

Upload a recording to discover aircraft Doppler curves, search historical flight tracks, and inspect the evidence. When the evidence cannot support a location, the result is inconclusive.

Search coverage: contiguous United States (CONUS), including smaller selected areas. Location goal: 100–500 m or better preferred; up to 1,000 m acceptable. Localization accuracy remains under evaluation.

New analysis

When did the recording start?

Enter UTC, including the date. A window is allowed. File creation and upload times do not establish recording time. Leave blank if unknown; analysis will request this evidence before searching.

Search area

Choose all of CONUS or a smaller area.

Enter coordinates, or left-drag on the map to draw a box. Right-drag or Shift-drag pans; scroll zooms. The rectangle must stay within the selected profile's bounds. Antimeridian crossings are unsupported.
