Is Here3 RTK compatible with FMUK66?

Hi, I’m currently using FMUK66 for my flight controller. I want to know is the FMUK66 compatible with Here3 RTK (not GPS)? Because when the RTK status turns to RTK streaming, I only get 3D Fixed instead of RTK Fixed. Are there any solutions to solve this issue?


What firmware do you use?

Is PX4 firmware

I guess it might be a firmware issue.
May I know what gps unit did you use ?
Can you please do a swap test with APM or different hardware ?
