GNSS Antenna Height

GNSS Toolbar | Antenna Height

The antenna settings are used to calculate or enter the height of the antenna phase center above the ground. You can enter the true height (if it is known) or enter the measured height and any horizontal or vertical offsets and have FieldGenius calculate the antenna height for you.

Depending on the model you've selected, manufacturer specific antenna offsets will be listed. If your specific antenna model is not listed, you can select "User Supplied" and specify appropriate offset measurements. For more detailed information about these offsets, refer to your users guide for your receiver.

The true height is simply computed by the use of Pythagoras' theorem:

TrueHeight = VerticalOffset + sqrt( (MeasuredHeight)2 - (HorizontalOffset)2 )

You can change the true or measured antenna height at any time, on the Store Point screen when storing your GNSS shots.
