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]

Overview

PX4 supports the following features:

  • Support for multiple vehicle types, including fixed-wing aircraft, multicopters, helicopters, rovers, boats, and underwater vehicles[4]
  • Fully manual, partially assisted, and fully autonomous flight modes[5]
  • Vehicle stabilization
  • Waypoint navigation
  • Integration with position, speed, altitude, and rotation sensors[6]
  • Automatic triggering of cameras or external actuators[7]

PX4 is capable of integrating with other autopilot software, such as the QGroundControl ground control station software,[8] via the MAVLink (Micro Air Vehicle Communication) protocol.[9]

PX4 is open-source and available under a BSD-3-Clause license.
