I have a Trimble R10 and need to upload static sessions to OPUS. What is the correct measurement that I need to use? Do I need to reference the ARP or Phase Center?

OPUS assumes ARP and makes you manually enter its height above the mark (not slant).  There are drawings on the NGS site (when it is available) showing where the ARP is for most models.  It is usually the bottom where an antenna screws onto a pole, but I am not familiar with that model.

The phase center is a point in an electric field. So that's not something you can measure. Not with a tape measure, anyway. You want the ARP, which is always the mounting point.

I think OPUS is looking for the height at the top of the quick release/ bottom of antenna (0.05 m up from BQR)

ARP is what you're looking for.
