How to set Moving baseline using dual Here4 gps on QGroundControl(with px4 Autopilot firmware)

Hello. I’m using here4 gps.

I want to set Moving Baseline using dual here4 gps.

My CubeOrange+ has PX4 firmware installed.

In this homepage, I can see ‘2. Using with PX4:‘ section.

But, in ‘7. Moving baseline’ section, there is no method to set the moving baseline based on the px4 firmware(with QGroundControl)

Conclusion, I hope to set Moving baseline using dual Here4 gps on QGroundControl(with px4 Autopilot firmware)

In my case, what can I do? how to set that?

Thank you.

The instructions for PX4 are here:

Try to work through this and let me know whether it works.
