Viva Series, Antenna Heights 282
13 Antenna Heights
13.1 Overview
Description 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 variations.
For most operations, pre-configured standard settings in the instrument can be used. They
automatically take the vertical phase centre variations into account.
Vertical or slope height Only vertical antenna heights measured to the Mechanical Reference Plane are accepted.
