For carriers other than those shown in the diagram above, the dimensions
must be determined.
Except for Leica standard antennas plus accessories, the vertical offset must be
measured. This value must be entered in the antenna setup record.
Tripod Setup
•
One of the Leica standard antennas is used, for example GS15. All former
Leica antenna types are supported.
Leica standard accessories are used.
•
a
GS_034
The vertical height reading is the height difference between the ground mark
and the bottom end of the height hook. It is determined using the height
hook.
1.
Determine the vertical height reading using the height hook.
2.
For Leica standard antennas plus accessories, the vertical offset is
0.36 m for a Tripod setup and 0.2545 m for a Tripod Short setup.
•
Determine the antenna type.
At the beginning of a survey, enter the vertical height reading into the
•
instrument.
The vertical offset is stored in the antenna setup record for all tripod set-
•
ups and will automatically be taken into account. It does not need to be
entered.
Refer to 24.1 Overview for the vertical phase centre offsets.
•
For other than the carriers shown in the diagram above, the dimensions must
be determined, the vertical offset must be adapted and entered into a new
antenna record.
