Antenna Heights
24.1
Overview
The height of the GNSS antenna above a point consists of three components:
•
the vertical or slope 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.
Only vertical antenna heights measured to the

lane are
accepted.
This table is an overview of required measurements depending on antennas,
setup and accessories. All former Leica antenna types are supported.
