a virtual antenna model in this field to emulate a GNSS
antenna other than the one really used.
Choosing a virtual antenna different from the one really
used affects the raw data as if they had been collected
by the virtual antenna, instead of the real one.
When the rover does not have to log raw data, select
“Off” in this field as there is no point using a virtual
antenna in this case.
• Set the parameters relevant to the GNSS constellations
used by the receiver:
– Position Elevation Mask: Choose the elevation angle
above the horizon creating the desired reception mask.
After setting this angle, any satellite seen from the
rover with an elevation angle less than the specified
one will be rejected from the list of usable satellites.
The default value is 5°.
– GPS, GLONASS, SBAS, QZSS, GALILEO: Enable the
options corresponding to the constellations you want
the receiver to work from.
• You can now click on the Configure button to save all the
changes made but remember you have to complete the
content of this page depending on how the receiver will
get its RTK corrections. Several typical applications are
listed below and described one after the other in the next
sections:
– Internal radio
– Direct IP via modem
– Direct IP via Ethernet
– NTRIP client via Ethernet
– RTK corrections received on port A, B or F
– Rover operating in Flying RTK mode.
– Rover operating in Hot Standby RTK.
