Using the GS09 Antenna

Understanding Antenna Heights

• The height of the GNSS antenna above the point consists of three components:
• the vertical height reading,
• the vertical offset,
• the vertical phase centre variations.
• For most operations, pre-configured antenna settings in CS09 field controller can
be used. These settings take the vertical phase centre variations into account.
Leica GS09 accepts vertical height readings to the Mechanical Reference Plane, MRP.
These are handled automatically in the standard antenna records. The antenna cali-
brations 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.
