RTK Base Setup
A typical base setup is described in this section in which:
• A conventional tripod is used
• A Thales U-Link radio is used for the data link
• RTK corrections data are transmitted in Ashtech CPD
(DBEN) format
• An external 12-V DC battery is used for powering both
the Z-Max.Net base and the U-Link transmitter
• A Bluetooth-enabled field terminal (MobileMapper CE)
is used, running the FAST Survey software, to set up the
base.
For other base configurations, it’s easy to extrapolate from
the instructions given below, knowing that configuring a
base always implies: 1) entering its geographical location
and 2) defining the data link.
Choosing the Installation Site
The installation site should offer the best possible GPS
reception conditions. The GNSS antenna should have a
clear view of the sky in all directions. There should be no,
or a minimum of satellite obstructions in the vicinity.
Setting Up the RTK Base
1. Connect the system components (power module, GNSS
antenna and V-module) as explained on
page 9.
Because a UHF radio transmitter is used for the data link,
a V-module, and not a communication module, can be
attached to the right side of the receiver module.
2. Center and level the tripod over the ground mark.
