Measuring Antenna Height
The receiver calculates the coordinates of the antenna’s phase center. To determine the coordinates of the
station marker, specify the following:
•
measured height (H) of the bottom of the receiver above the station marker (refer figure 21)
•
model of the receiver (GCX2) used
•
Any necessary antenna phase center adjustments, based on the antenna model, is automatically applied. This
adjustment, when combined with accurately measured height and measurement methods, enables correctly
computed reference marker coordinates.
Obtain Accurate Antenna Height
1. Measure the height of the bottom of the receiver or Antenna Reference Point (ARP) above the control
point or marker.
