Hawkeye is a real-time 3D flight visualizer for PX4. Replay recorded ULog flights or watch live MAVLink telemetry in a fast, clean 3D world built on Raylib.

OFFICIAL APP
Hawkeye is the official PX4 flight visualizer, published by the Dronecode Foundation. Apps built from this source by others are community forks. They are not affiliated with or supported by Dronecode.

REPLAY ULOG FLIGHTS
Import .ulg flight logs and play them back with full transport controls: pause, seek, and playback speed. Imported logs are kept in your replay library for quick access.

WATCH LIVE TELEMETRY
Point your vehicle or simulator at your device and start a session. Hawkeye listens for MAVLink over UDP (default port 19410) and renders vehicle state as it streams in. The app shows the exact endpoint to send to.

FLY WITH UP TO 16 VEHICLES
Load multiple logs together and analyze them side by side with ghost overlays, automatic deconfliction, takeoff alignment, and real-time correlation between drones.

CAMERAS AND VIEWS
Chase, FPV, and free-fly cameras plus fixed top, bottom, front, back, left, and right views, all one gesture away on the radial view wheel. A full flight HUD shows heading, attitude, altitude, ground speed, and vertical speed at a glance.

BUILT FOR PX4
Reads standard PX4 ULog files and HIL_STATE_QUATERNION MAVLink streams from SITL simulators or real vehicles. Quadcopter and VTOL vehicle models are rendered from live attitude and position data.

OPEN SOURCE
Hawkeye is free and open source under the BSD-3-Clause license. Desktop builds for macOS, Linux, and Windows are available too. Source, documentation, and issue tracker: https://github.com/PX4/Hawkeye

NOT A FLIGHT SAFETY DEVICE
Hawkeye is a visualization and analysis tool, not a flight safety device. Do not rely on it to operate an aircraft or to make in-flight decisions.
