Hello,

I am trying to create a Rover-Base RTK system as outlined in this tutorial: [https://learn.sparkfun.com/tutorials/se … over-setup](https://learn.sparkfun.com/tutorials/setting-up-a-rover-base-rtk-system?_ga=2.23674425.2017833677.1612196014-1860717908.1611264190#rover-setup)

I’ve followed the tutorial up to soldering the radio to the rover. However, when I have both modules powered on and I check the fix type of the rover (UBX-NAV-PVT), it says “3D Fix” instead of “RTK Fix” or “RTK Float”.

What else could be wrong? Any help into this matter would be greatly appreciated.

Thank you
