Antenna Heights: Understanding Antenna Heights 3.10.1

Description- The height of the GNSS antenna above a point consists of three components: 

• the vertical height reading,
• the vertical offset,
• the vertical phase centre offset.
For most operations, pre-configured standard settings in the instrument can be used. They automatically take the vertical phase centre offsets into account.

ARP: The antenna accepts vertical height readings to the Antenna Reference Plane,
ARP.

Vertical phase centre variations

These are handled automatically in the standard antenna records. The antenna calibrations to determine the phase centre variations were executed by Geo+ +® GmbH.

☞ Pillar setup. For other than the GRT146 carrier, the dimensions must be determined and the vertical offset must be adapted.

☞ Tripod setup. For height measurement devices other than the height hook, the dimensions must be determined and the vertical offset must be adapted.

☞ Pole setup. For other than Leica poles, the dimensions must be determined.

☞ Mast setup. The dimensions of the mast must be determined.
