PX4 is an open source flight control software for drones and other unmanned vehicles. The project provides a flexible set of tools for drone developers to share technologies to create tailored solutions for drone applications. PX4 provides a standard to deliver drone hardware support and software stack, allowing an ecosystem to build and maintain hardware and software in a scalable way.
Historically, PX4 grew from the PIXHAWK project at ETH Zurich, which the PIXHAWK MAV was specifically designed to be a research platform for computer vision based flight control. The project now counts more than 300 global contributors and is used by some of the world’s most-innovative companies, across a wide range of drone industry applications. The open source community around the Pixhawk open autopilot hardware and the PX4 flight stack is the largest industry-backed development community in the drone space today.
PX4 is part of Dronecode, a non-profit organization administered by Linux Foundation to foster the use of open source software on flying vehicles. Dronecode also hosts QGroundControl, MAVLink & the SDK.
