Measuring Antenna Height  

 32 

P/N: 1016293-01

System Setup

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 (see Figure 24)

•

model of the receiver (GCX3) 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.

Obtaining Accurate Antenna Height

1. Measure the height of the bottom of the receiver or Antenna Reference Point (ARP) above the 

control point or marker.

Figure 24: Obtaining Accurate Antenna Height

Topcon software only requires input of measured height (H) to compute coordinates of the 

Antenna phase center of the receiver. For precise antenna height, it is recommended that 

you use the vertical measurement method shown in Figure 24.
