How gyroscope and accelerometer work in a drone?
For drone applications , both a gyroscope and an accelerometer are essential — and they’re typically used together in an IMU (Inertial Measurement Unit) . Here's how they work in a drone: Why Both Are Needed in a Drone Sensor Role in a Drone Accelerometer Measures linear movement and tilt (e.g., helps detect up/down, forward/backward) Gyroscope Measures rotation rate (e.g., helps stabilize pitch, roll, yaw during flight) Together, they allow the drone to: Maintain stable flight Perform flips and turns Auto-correct position against wind or vibration Enable GPS-free hovering and indoor flight Recommended Sensor: IMU Modules For drones, use a 6-axis or 9-axis IMU , which combines: 3-axis accelerometer 3-axis gyroscope (optional) 3-axis magnetometer for compass/heading Popular IMUs for drones: Sensor Type Notes MPU6050 6-axis Very common, good for hobby drones MPU9250 9-axis Adds magnetometer for better heading ICM-20948 9-axis Hig...
