4.1. HOW TO CONFIGURE THE ASTERX-U3 FOR RTK
Step 3: Con fi gure the NTRIP connection
Using a cellular connection, you can get RTK correction data from an NTRIP service. Figure 4-7
shows the settings required to retrieve correction data from the Septentrio NTRIP Caster.
Select ‘Client’ from the drop-down
Mode menu. The Caster, Port, User Name and Password
should be provided by the NTRIP service. NTRIP Casters typically provide multiple correction
data streams known as
Mount Points . When a connection has been made to the Caster, the
‘Mount Point’ drop-down list will become active. In this example, the FLEPOS_HOEG stream
has been selected, the details of which are shown in Figure 4-8.
When using correction data from a virtual base station it is often necessary to provide your
position to the NTRIP Caster in the form of an NMEA GGA message. This can be con
fi gured
in the ‘ Send GGA to caster ’ drop-down list.
