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.
