您需要在首次使用时,或者如果飞行控制器方向改变时,校准您的加速计。 否则您不需要重新校正(除非可能在冬季, 如果你有一个飞行控制器,在工厂中没有 的热校准

:::note 加速计校准效果不佳,通常通过飞行前检查和防护被拒绝的消息捕获(典型的QGC 警告提示“高加速计偏差”和“一致性检查失败”)。 :::


This is similar to compass calibration except that you hold the vehicle still (rather than rotate it) in each orientation.


QGroundControl will guide you to place and hold your vehicle in a number of orientations (you will be prompted when to move between positions).

The calibration steps are:

  1. Start QGroundControl and connect the vehicle.

  2. Select "Q" icon > Vehicle Setup > Sensors (sidebar) to open Sensor Setup.

  3. Click the Accelerometer sensor button.

    Accelerometer calibration

    You should already have set the Autopilot Orientation. If not, you can also set it here.


  1. Click OK to start the calibration.

  2. Position the vehicle as guided by the images on the screen. Once prompted (the orientation-image turns yellow) hold the vehicle still. Once the calibration is complete for the current orientation the associated image on the screen will turn green.


The calibration uses a least squares 'fit' algorithm that doesn't require you to have "perfect" 90 degree orientations. Provided each axis is pointed mostly up and down at some time in the calibration sequence, and the vehicle is held stationary, the precise orientation doesn't matter. :::

Accelerometer calibration

  1. Repeat the calibration process for all vehicle orientations.

Once you've calibrated the vehicle in all the positions QGroundControl will display Calibration complete (all orientation images will be displayed in green and the progress bar will fill completely). You can then proceed to the next sensor.
