For other height measurement devices than the height hook, the dimensions
must be determined and the vertical offset must be adapted.
For other than Leica standard antennas, the vertical offset must be measured.
It must be entered in the antenna setup record.

Pole Setup
•
One of the Leica standard antennas is used, for example GS15. All former
Leica antenna types are supported.
•
Leica standard accessories are used.

Vertical height reading,
2.00 m for the fully extended
Leica telescopic pole.
Vertical offset = 0.00 m
The vertical height reading is the height difference between the bottom end
and the top end of the pole. Usually, this height difference is a fixed value.
•
At the beginning of a survey, enter the vertical height reading into the
instrument. A standard rover configuration with a standard antenna setup
record for a pole setup uses the value of 2.00 m already as default.
•
The vertical offset of 0.00 m is stored in the antenna setup record for a
pole setup 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 Leica standard poles, the dimensions must be determined.
For other than Leica standard antennas, the vertical offset must be measured.
It must be entered in the antenna setup record.
