In Leica GNSS world, there are things to remember in order to get the correct antenna height: MRP (Mechanical Reference Plane), Vertical phase centre offset for L1, Vertical phase centre offset for L2.
In Fieldgenius world, there are corresponding values but not of same terms: ARP and APC. What is ARP or APC? Any idea?
Thank you.

ARP is antenna reference point and is usually the bottom of the threaded mounting (but maybe not always). US NGS uses measurements to this point as an input to OPUS.
APC is antenna phase center, and is a possibly non-physical point inside the assembly, and also possibly not the same for L1 and L2 or other GNSS signal component.
