PX4 autopilot is an open-source autopilot system oriented toward inexpensive autonomous aircraft.[1]

Low cost and availability enable hobbyist use in small remotely piloted aircraft. The project started in 2009[2] and is being further developed and used at Computer Vision and Geometry Lab of ETH Zurich (Swiss Federal Institute of Technology) and supported by the Autonomous Systems Lab and the Automatic Control Laboratory. Several vendors are currently producing PX4 autopilots and accessories.[3]


An autopilot allows a remotely-piloted aircraft to be flown out of sight. All hardware and software is open-source and freely available to anyone under a BSD license. Users can modify the autopilot based on their own special requirements.

The open-source software suite contains everything to let airborne system fly including:

  • QGroundControl[4] and MAVLink Micro Air Vehicle Communication Protocol[5]
  • 2D/3D aerial maps (with Google Earth support)
  • Drag-and-drop waypoints

Other open-source robotics projects similar to PX4 include:
