Here3 moving baseline issues

Hi there,

I am trying to implement moving baseline using a couple of Here3s I had on hand from an older project. I have followed the instructions provided on ArduPilot’s respective documentation. Unfortunately I keep running into “GPS: no fix” and “No yaw available.” errors. Both modules work as expected when used separately.

Here are how my parameters configured in case this is a config issue.

I apologize if this has been discussed here before; however, although I have seen many posts about moving baseline issues with Here3+, I am yet to find any explicit statements about whether Here3 has moving baseline support or not.

In the case where Here3 indeed does not support moving baseline what are good alternatives with this functionality? For context my setup includes pixhawk4, raspberry pi 3+, Here+ RTK Base along with the Here3.

Thanks in advance.
