Setting up as a Real-Time Base

The equipment setup described is used for real-time base stations with the
need of optimal radio coverage. Raw observation data can also be collected for
post-processing.
The GS18 instrument can be programmed with the field controller before use
which can then be omitted from the setup.
The connection between GS18 and the field controller is made via Bluetooth.
The radio antenna (GAT28) is directly mounted downwards facing at the GNSS
antenna. Alternatively, the radio antenna (GAT1/GAT2) can be mounted on the
antenna arm (CA41) which clips to the GNSS antenna.
