If you refer to the chart in link below. min 4 hours, but 7-8 hours prob best gonna get using OPUS.

The GPS only result (Mark’s post) is showing a higher fixed ambiguity percent, which is good. However, the estimated RMSE is higher, which is bad. I would probably go with the 3 constellation report as more accurate as it’s based on a lot more observations and estimates a lower RMSE.
Note that your results might improve if you wait a few days and resubmit them to OPUS.
To get a more accurate result, you can take several observations over different days with different satellite geometries and then average them together.
GPS only: ORTHO HGT: 27.607(m)
3 constellations: HO Height: 27.953(m)

Thank you for the thorough explanation.
I may have the chance to go back and do another measurement and just leave the receivers overnight.
Oh, so for the 3 constellation result, the error is 0.282 m?
That is probably the estimated error window based upon the math. The actual error can be different.
