Mastering FPV Drone Sensor Calibration — Gyro, Accelerometer, Compass: Accurate Sensor Settings for Stable Flight
Photo by Ferntech DJI on Unsplash Is your drone constantly drifting to one side? Is your goggle footage shaky? The problem might not be the components, but the sensors. The sensors mounted on an FPV drone's flight controller (FC) are the "brain" that detects movement and maintains attitude. However, many beginners skip sensor calibration after assembly, which often leads to flight issues. In this post, we will cover everything you need to know about understanding and correctly calibrating FPV drone sensors. Roles and Types of Sensors An FPV drone's FC typically contains three primary sensors. First, the Gyroscope detects the drone's rotational speed. By measuring rotation on the roll, pitch, and yaw axes, it provides the most critical data for PID control. Without accurate gyro calibration, the drone might perceive itself as tilted when it is actually level, or it might fail to recognize an actual tilt. Next is the Accelerometer. This sensor detects gravi...
