## About

PX4 is an open-source autopilot stack for drones and unmanned vehicles. It supports multirotors, fixed-wing, VTOL, rovers, and many more experimental platforms from racing quads to industrial survey aircraft. It runs on [NuttX](https://nuttx.apache.org/), Linux, and macOS. Licensed under [BSD 3-Clause](LICENSE).

## Why PX4

**Modular architecture.** PX4 is built around [uORB](https://docs.px4.io/main/en/middleware/uorb.html), a [DDS](https://docs.px4.io/main/en/middleware/uxrce_dds.html)-compatible publish/subscribe middleware. Modules are fully parallelized and thread safe. You can build custom configurations and trim what you don't need.

**Wide hardware support.** PX4 runs on a wide range of [autopilot boards](https://docs.px4.io/main/en/flight_controller/) and supports an extensive set of sensors, telemetry radios, and actuators through the [Pixhawk](https://pixhawk.org/) ecosystem.

**Developer friendly.** First-class support for [MAVLink](https://mavlink.io/) and [DDS / ROS 2](https://docs.px4.io/main/en/ros2/) integration. Comprehensive [SITL simulation](https://docs.px4.io/main/en/simulation/), hardware-in-the-loop testing, and [log analysis](https://docs.px4.io/main/en/log/flight_log_analysis.html) tools. An active developer community on [Discord](https://discord.gg/dronecode) and the [weekly dev call](https://docs.px4.io/main/en/contribute/).

**Vendor neutral governance.** PX4 is hosted under the [Dronecode Foundation](https://www.dronecode.org/), part of the Linux Foundation. Business-friendly BSD-3 license. No single vendor controls the roadmap.

<sub>…and many more: helicopters, autogyros, airships, submarines, boats, and other experimental platforms. These frames have basic support but are not part of the regular flight-test program.

## Quick Start

```bash
git clone https://github.com/PX4/PX4-Autopilot.git --recursive
cd PX4-Autopilot
make px4_sitl
```
