Dual GPS antenna for yaw

Hi everyone, I am trying to build a new surface boat, the idea would be to use two onboard GPS antenna like this one to have a good yaw. One would be at the very front of the boat and the other at the very end so that the distance between them is maximum and the yaw is more precise.

Until now I thought I would use a board like this to plug my two GPS antennas and then link the board to the “GPS” port of my pixhawk and then set two GPS in the parameters.

But then I saw this page and now I am a bit lost on the way I should configure everything. Can someone tell me if I sould plug my antenna directly on the pixhawk, or if I should use a board like the PX1172RH or not, and then which set of parameter I should use. Because I don’t think my case is the moving baseline, is it ?

Thank you in advance !

If this can help, I use a raspberry pi with rpanion has a companion computer and rtk correction through ntrip…

You are describing a moving baseline configuration and linked the correct documentation to configure it.
