The chosen antenna model can now be seen on the place of the  Please select!  button.

 

Selecting an external antenna

   

 

L1 Offset: Vertical Phase Center Eccentricity for L1. This value in mm refers to the vertical distance between the top of the pole (or the base of the antenna) and the L1 phase center of the selected antenna. The L1 Offset is = 0 mm if there is no selected external antenna.

 

Rod height: Height of the rod in meters. The Rod height is = 0 m if the there is no selected antenna. Default Rod height = 2 m.

 

Antenna height = Rod height + L1 Offset. It is global variable (for all layers) and its value will be deducted from the HAE (Height Above Ellipsoid).

About the height calculation please also have a look at this tutorial at http://forum.digiterra.hu/viewtopic.php?f=59&t=308

Please note, that the Antenna height is not applied on the GNSS Survey dialog as in version 6, but you can still apply different Up/Down offset values there for any layer.
