The Role of the Gyroscope
The gyroscope tells the flight controller how much the drone is tilting.
If the drone starts to lean left, the gyroscope senses the movement and signals the motors to correct it.
This happens many times every second, keeping the drone steady even in wind.
The Role of the Accelerometer
The accelerometer senses movement and direction changes.
It helps the drone know whether it’s going forward, backward, or climbing.
It works with the gyroscope to prevent wobbling and drifting.
The Role of the Compass
The compass acts like a navigator, showing the drone which direction it’s facing.
Without a properly calibrated compass, the drone might lose its sense of direction or spin out of control.
Why Calibration Is Important
Sensors can become slightly inaccurate due to temperature, magnetic fields, or vibrations.
Calibration resets them to “zero,” ensuring correct readings.
A well-calibrated drone means smoother, safer, and more predictable flights.
