**Tips for Accurate Calibration**

* **Ensure Strong GPS Signa**l: Perform calibration in open areas with minimal interference.
* **Use Landmark**s: Identify easily recognizable objects (buildings, trees, road edges).
* **Recalibrate as Needed**: Especially when operating in a new location or if GPS drift occurs.
* **Test Before Operation**: After calibration, perform a short hover or test run to verify map accuracy.
