QGroundControl is used to install firmware onto the flight controller hardware, specify an airframe, and configure the core sensors that PX4 needs to be present on every vehicle (compass, GPS, gyro etc.).
Before starting this section you should Download QGroundControl and install it on your desktop computer (QGroundControl does not support vehicle configuration on mobile platforms).
This section contains essential configuration topics:
- Sensor Orientation
- Airspeed (fixed-wing/VTOL)
- Level Horizon Calibration
- Radio Setup
- Joystick Setup
- Flight Modes (Optional)
- Battery (optional)
- Safety (optional)
The video below shows the calibration process in detail.
If you need help with the configuration you can ask for help on the QGroundControl Support forum.
