Pixhawk2 and Here+ RTK Connect

I’m trying to test RTK modules. I set the environment that pixhawk2 cube black with ardupilot connect here+ rtk module. Is it correct below picture?

If I want to use NTRIP features, that connection is correct? Another interface connect was needed?

yes, it is correct. It will work

Thank you~!

I connect pixhawk2 with here +

And, gps/rtk injection was checked in mission planner.

After, I can see “3D fix” → “rtk float”

But, It is not occur “rtk float” → “rtk fix”

why?? I don’t know… More work was needed?
