Enter the height measurement from the tip of the pole to the bottom of the Catalyst receiver, as in the image at right. The correction for the offset from the bottom of the pole mount adaptor to the antenna phase center (the point where the GNSS measurement is made) is automatically applied.

Enter the height measurement from the tip of the pole to the bottom of pole mount, as in the image below. The correction for the offset from the bottom of the pole mount adaptor to the antenna phase center (the point where the GNSS measurement is made) is automatically applied.

If you are using the SiteVision Integrated Positioning system without a pole and place the unit on the ground during measurements, set the pole height to zero and the system will apply the offset for the height of the unit without the pole mount adaptor.
