The Open VDL2 & ACARS Datalink Network LIVE VDL2

Decode what aircraft are actually saying overhead. Stream real-time position reports, surface takeoff and approach milestones, OOOI gate times, and AMDAR weather across a global open datalink network.

💡 One Windows Software Package: FlightPatch runs both ADS-B and VDL2/ACARS. The software is identical—simply plug in a 136 MHz airband antenna instead of 1090 MHz!

Airfield Takeoff Deficit Rankings

Line-of-sight VHF signals from cruising aircraft easily reach 200+ nautical miles, but surface roll, taxi, and initial takeoff climb are shadowed by terrain and horizon. We need feeders directly on or near commercial airfields to capture low-altitude positions and gate departure milestones.

3D-Printed Window-Mount Antenna

No roof access needed. Our 3D-printed window mount attaches via 3M Command strips, cradles the RTL-SDR dongle directly at the antenna for zero coax loss, and feeds your Windows PC over active USB.

What Aircraft Are Saying Overhead

📍 Overhead & Surface Position Reports High-frequency aircraft position reports, runway rollout, oceanic and remote sector waypoints, and terminal approach fixes directly from onboard navigational computers.
🛫 Takeoff & OOOI Departure Timestamps Exact gate departure (OUT), runway lift-off (OFF), touchdown (ON), and gate arrival (IN) operational timestamps transmitted directly from airborne avionics.
🌤️ AMDAR Meteorological Observations Commercial airliner automated wind vector, ambient temperature, static air pressure, and high-altitude turbulence reports updated on climb and cruise.
🔓 Free Open API & Daily Parquet Data Direct REST endpoints, real-time WebSocket firehose stream, and daily consolidated Parquet files for aviation analytics and research—100% free and open.
