Using the Web Server
• Set the parameters relevant to the GNSS constellations
used by the receiver:
– Recording and Output Elevation Mask: Choose the
elevation angle above the horizon creating the desired
mask. After setting this angle, any satellite seen from
the base with an elevation angle less than the specified
one will be rejected from the list of tracked satellites.
The recording elevation mask affects the
measurements recorded in G-files and the differential
messages generated by the receiver. The default value
is 5°.
– GPS, GLONASS, SBAS, QZSS, GALILEO: Enable the
options corresponding to the constellations you want
the receiver to work from.
• In the Internal Radio Port D, if the internal radio (ADL
Foundation) is present and used, enable the On check box
to power this radio on.
• You may now click on the Configure button to save all the
changes made but remember you will have to complete
the content of this page to tell the receiver how to make
the generated data available to users.
But before that, you need to define which data the
receiver has to generate, which output rate and which port
to use for each of the data messages. See Defining the
Data Generated by a Base on page 70.
Then use one of the typical applications described below
to make the data available to users:
– Radio transmitter
– Direct IP via modem
– Direct IP via Ethernet
– NTRIP server via modem
– NTRIP server via Ethernet
– RTK corrections delivered on port A, B or F
– Ethernet data streaming.
Defining the Data
Generated by a
Base
Depending on your application, you will have to define
different types of data messages as well as the ports through
which they will be delivered.
Three categories of output data are possible (NMEA,
differential and raw data) but only the use of differential and
raw data messages makes sense in a base.
