The PX4 flight stack is part of the Dronecode platform, an end-to-end solution for building and managing Unmanned Aerial Vehicles (AUV).
The platform has several parts:
- PX4 Flight Stack: The flight control system (autopilot).
- MAVLink: A highly efficient, lightweight and blazing fast robotics communication toolkit.
- QGroundControl: Modern, mobile and desktop user interface to configure the system and execute flights.
A number of other projects work with the platform including: DroneKit, ROS, FastRTPS, AirSim, Gazebo, and RViz (to name a few).
