## RTK Setup in QGC

1. After the [base station has been setup](/inspired-documentation/products/accessories/inspired-flight-nav-rtk-base-station/base-station-gear-setup.md).
2. Open QGC on the laptop that the Base Station is plugged into.&#x20;
3. QGC will automatically recognize the base station and begin trying to acquire a fixed signal.

7. Restart QGC by closing the app and reopening it again.
   1. Swipe right from far left of the screen, then press the square button in the native android menu
   2. Press the x on the IGC app to close the app.&#x20;
   3. Reopen the app by pressing the IGC logo
8. Click on the red RTK icon to verify that the Current Accuracy is decreasing. Note that it may take several minutes for this to occur.&#x20;

{% hint style="info" %}
If the accuracy continues to remain stagnant, restart QGC again.
{% endhint %}

9. Once the Base Station has reached the desired accuracy, the RTK symbol will change to white, indicating a ‘fixed’ signal.&#x20;
