Connect your Flipper Zero to your computer using USB and visualize signal recordings on map.
Flipper files should include Lat: and Lon: lines. Custom firmwares like Momentum and RogueMaster automatically add these lines using GPS module (via GPIO). For the official firmware or Unleashed, it should be done manually I hope some day they'll implement same features. You can add location info using Flipper mobile app or directly edit them on SD card.
