Trimble Catalyst and Trimble Corrections Hub will output coordinates in ITRF2014 current epoch.  

If you use your own reference station then you need to understand the coordinate system of your correction source, as your position will be based on the datum your correction source is using.

The height value within each position from Trimble Mobile Manager, and the Android location service, will already have the antenna phase centre offset (2.433 inches or 61.8mm) correction applied to the bottom of the black plastic antenna mount.

Any additional height (if pole mounted for example) will need to be applied via your chosen software application
