Leica Captivate - Antenna Reference Planes, ARP

For Leica antennas: For non-Leica antennas:
Are handled automatically in the
standar
d antenna records.
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.
The antenna calibrations to determine the phase centre offsets of all Leica
ant
ennas were executed by Geo++® GmbH.

•
is where the an

•
is where the phase centre offsets refer to.
•
varies for different antennas.
