When doing the Time Variable Transformation in Geodesy HYPACK does not account for vertical. Therefore a z value under the RTK Tide method needs to be entered. There is a spreadsheet available for the techs to enter all the position information and the spreadsheet calculates a value for the customer to enter it as the Orthometric Height Correction in Geodesy. It would be really nice for this to be done on the fly or another more professional option to add for the users to use.
The spreadsheet is here: G:\CustomerService\Documents\ITRF2014 spreadsheet
