Do a site calibration using local benchmarks (with ortho heights) or a network adjustment constraining to the same. You will need to have an orthometric height source near the site. Review the help documentation for specifics on how to do this. The site calibration can be done on Trimble Access or TBC. It can be a tricky thing, so make sure to read the documentation on it.

Subject: Estimation of orthometric elevation
Hi everyone!
I 'm working in TBC for the first time with RTK GPS data. I know that I have to apply a geoid model, but this model are global.
How can adjust the ellipsoid elevation to precise orthometric elevations for local points in TBC?
Kind regards
