PX4 is an open source flight control software that powers any vehicle from flying drones to ground vehicles.

The collaborative project is participated by industry and academic from worldwide. It enables developers create custom drone operating systems with a flexible core. Whether running a racing drone or a drone fleet, PX4 can be customized and tailored to fit your need. Along with other tools from Dronecode stack, a complete end-to-end UAV platform can be built with an IP-friendly permissive BSD license.
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.
