Installing a Resolute
When installing a Resolute it is important to choose the installation site thoughtfully. It should
be noted that there are differences when installing Rovers, Bases, and Reference receivers which
will be highlighted in the following sub sections.
RTK Radio Network Design
Before leaving the office, if your unit includes a radio for broadcasting or receiving corrections,
best practice is to determine the radio network for your device. Consider any already installed
units that you want to avoid disturbing or include in your network. See the example radio
network drawings in the
Appendix E in addition to the RTK Radio Network Design section for
more information. It is easiest to configure the radios in the office before leaving, but
configuration is possible to do in the field. Record the radio channel numbers of various units for
future reference.
Easiest installation order is generally from Base to NorthStars (if utilized) to Rovers as this allows
the installer to confirm corrections are being received at the Rovers before concluding install.
Installing the GNSS Antenna
The GNSS Antenna is the measuring point of the Resolute. Installing the antenna in ideal
conditions will increase the performance of your units. The antenna should ideally be installed
with a 180 degree uninterrupted view of the sky. If this is not possible, maximizing the volume of
the sky in view is advantageous. Keep in mind the majority of GNSS satellites do not pass directly
overhead, but travel closely to the horizon. The GNSS antenna will perform better if metallic
objects and other reflective surfaces are not in the immediate vicinity. This means the antenna
should be mounted one meter off the ground or other surface if possible. It should also be above
surrounding buildings if possible.
For RTK Rovers and Reference stations, GNSS antenna should be monumented to the desired
landmark to be measured. This means that the antenna should be attached in such a way that if
the landmark moves the antenna will be moved by the same amount. Keep in mind of the thermal
expansion when mounting the antenna to the landmark, especially for fine deformation
monitoring.
If an RTK Base is being installed, the antenna should be monumented to a piece of land that is
not moving. Bedrock if available is great for this. Any movement of the Base antenna will present
itself as movement of the Rovers in the data.
