5. Configuring the Receiver Technical Reference Manual-4.0.0en
Antenna
Select the Antenna configuration that
you are using.
Ant. Name - Displays and selects the
currently selected antenna setup.
Vert Offset - Displays the vertical
offset defined in the Antenna setup
(Ant Name).
Deflt Hgt - Displays a default height
for the Antenna setup. This is of little
use for Static or Rapid Static applica-
tions where the Antenna height differs
with each setup.
Meas Type - Also, enter the means
by which the Antenna height was
measured. For the majority of GPS
Antennas (including all Leica anten-
nas), this will be Vertical. The height
of some non-Leica GPS antennas
can only be measured by taking the
slope distance to the outer edge of
the Antenna. If this is the case, select
Slope and enter the averaged value.
You will then be required to enter a
Horizontal Offset also. See Section
2.15.3 for more details on measuring
slope height.
To select an antenna setup, highlight
Ant. Name and press ENTER to
open the drop down box. All of the
existing antenna setups are listed.
You may select from this list or enter
your own Antenna configuration by
pressing the NEW (F2) key. Note that
the settings from the currently high-
lighted antenna setup are taken over
as suggested default values.
Most Static and Rapid Static Surveys
or Reference Stations are carried out
using a tripod or pillar setup.
When a factory default tripod setup is
chosen, the Vertical Offset is auto-
matically set at 0.36m. You will only
need to measure the height with the
height hook when setting up over a
point.
