Antenna Heights
For Leica antennas:
Are handled automatically in the
standard antenna records.
The antenna calibrations to determine the phase centre offsets of all Leica
antennas were executed by Geo++® GmbH.
Antenna Reference Planes, ARP
The Antenna Reference Plane
•
is where the antenna heights are measured to.
is where the phase centre offsets refer to.
•
varies for different antennas.

For non-Leica antennas:
Can be stored in a newly created
antenna record.
OR
Antenna records including azimuth
and elevation-dependent corrections
must be created using Infinity or
imported using the ANTEX format.
