The '''PX4 autopilot''' is an open-source system for autonomous aircraft. The project was started in 2009.
The '''PX4 autopilot''' is an open-source system designed for affordable autonomous aircraft. Its cost-effectiveness and widespread availability make it suitable for hobbyists operating small and remotely piloted aircraft. Originating in 2009, this project is continually evolving, with ongoing development and utilization at the Computer Vision and Geometry Lab of ETH Zurich (Swiss Federal Institute of Technology). It also receives support from the Autonomous Systems Lab and the Automatic Control Laboratory. Currently, numerous vendors are manufacturing PX4 autopilots and associated accessories.
 
==Overview==
PX4 supports the following features:
 
*Support for multipleMultiple vehicle types, including fixed-wing aircraft, multicopters, helicopters, rovers, boats and underwater vehicles<ref>{{Cite web |title=Airframes Reference - PX4 User Guide |url=https://docs.px4.io/main/en/airframes/airframe_reference.html#airframes-reference |access-date=2023-03-12 |website=docs.px4.io}}</ref>
