‘Antenna Height’ If the Base receiver is mounted on
a fixed height pole, select ‘Vertical’ and enter the
vertical distance from the Ground Mark to the
bottom of the antenna as shown in
blue
above.
If the Base receiver is mounted on a tripod and you
can’t make a direct vertical measurement, select
‘Slant’ and enter the slanted tape distance from the
ground mark to the bottom of the blue band that
separates the white top from the gray bottom as
shown in
red
above.
Set the ‘Elevation Mask’ to an appropriate elevation
for the horizon mask conditions at the Rover,
typically 10 degrees is appropriate.
1, 2 or 5 Hz Position Rate is good for stakeout.
Check ‘Use IMU’ if you want to use the internal
electronic bubble. If you enable IMU operation, the
position update rate is forced to 5Hz.

Click on the RTK tab:
Select ‘Device’ = ‘Internal UHF’.
The ‘Message Type’ should match the selection
made at the base. (If you don’t know the base
setting, don’t worry about it—the rover will
automatically figure it out.)
Leave ‘Use Any Base ID’ Checked!

Click on the Settings button (hammer / wrench) to
the right of the ‘Device’:
Always set ‘Sensitivity’ to ‘High’ on the Rover. (High
sensitivity results in the longest radio range.)
The ‘Protocol’, ‘Frequency’ and ‘Forward Error
Correction’ must match the base.
The Base and Rover channels don’t have to match,
but the ‘Frequency’ must match exactly!
