đŸ›Šī¸ What is QGroundControl?

QGroundControl (QGC) is a free, open-source ground control station (GCS) software used for configuring, monitoring, and controlling drones and unmanned vehicles (UAVs, UGVs, ROVs) that use open autopilot firmware like:

  • PX4
  • ArduPilot

It works on Windows, macOS, Linux, Android, and iOS.

    • Flight modes
    • Sensors

🔹 Step 3: Initial Setup

  1. Go to the Vehicle Setup tab (wrench icon on left side).
  2. Run through the required steps:
    • Airframe setup: Choose vehicle type
    • Sensor calibration: Accelerometer, compass, level
    • Radio setup: RC binding and calibration
    • ESC calibration
    • Flight modes

All steps are guided with on-screen instructions.


🔹 Step 4: Mission Planning (Auto Flight)

  1. Click on the Plan View (map icon).
  2. Add waypoints by clicking on the map.
  3. Set altitude, speed, camera actions, and more for each point.
  4. Upload mission to drone by clicking Upload.

🔹 Step 5: Flight Monitoring

  • Switch to Fly View (airplane icon).
  • Displays:
    • Map view of drone position
    • Live telemetry
    • Camera FPV (if available)
    • GPS info, altitude, speed, etc.
  • Use the on-screen virtual joystick (for mobile) or an external RC controller/gamepad (on supported platforms).

🔹 Step 6: Advanced Features

  • MAVLink Console: Send custom MAVLink commands
  • Analyze flight logs (via .ulg or .bin)
  • Customize parameters for tuning or upgrades
  • Geofencing and return-to-home configuration
