No special permissions needed, these are public broadcasts."
A $20 RTL‑SDR USB dongle with R820T2/RTL2832U chipset can receive commercial aircraft ADS‑B broadcasts on 1090 MHz. Zadig installs a WinUSB driver for the dongle; select Bulk‑In, Interface 0 and install or replace the driver. Download and extract the dump1090 Windows build to a simple path such as C:\dump1090. Open a Command Prompt in that folder and start dump1090 to decode ADS‑B messages. Virtual Radar Server displays decoded messages on a live map, showing flight numbers, GPS positions, altitudes, and speeds without cloud services or subscriptions.
