What is used to measure the angular accelerations around the pitch, roll, and yaw axis?

• A. Accelerometer
• B. Gyroscope
• C. Barometer
• D. Altimeter

Answer: (B)

Rotational motion around the aircraft’s three axes is tracked by a gyroscope. This sensor measures angular velocity, the rate at which the drone rotates about each axis—pitch, roll, and yaw. That information lets the flight controller know exactly how the drone is turning and to adjust motor outputs to keep or change orientation. Angular acceleration could be obtained by differentiating that rate over time, but the gyroscope’s primary output is angular velocity. In contrast, accelerometers measure linear acceleration, and barometers/altimeters measure altitude, not rotation.
