PX4

PX4 is the industry-standard open source flight control stack powering everything from racing drones to industrial heavy-lift VTOLs.

PX4 provides the flight control logic for the Dronecode ecosystem, running on NutX RTOS to deliver deterministic performance for autonomous vehicles. It integrates natively with the MAVLink protocol and QGroundControl, supporting diverse hardware like the Pixhawk 6C and Orange Cube. Whether you are tuning a 250mm FPV quad or a fixed-wing cargo drone, PX4 handles the complex sensor fusion (EKF3) and GPS-independent navigation required for professional-grade missions.
