8.1.3.8 NTRIP Client
The NTRIP client built into GNSS Compass can be used to connect to a network DGPS (Differential GPS, a
older standard for GNSS corrections of lower performance than RTK) or RTK service to stream correction data
to GNSS Compass for DGPS or RTK. The NTRIP client requires that GNSS Compass has an available internet
connection to the NTRIP Caster to function.
The source of the corrections data can be either your own base station, configured as an NTRIP Caster, or a
third-party service. Either way, you will need the login details for connecting to and authenticating with the
NTRIP Caster, and identifying the nearest mountpoint.
These steps are required:
1. Select Enabled.
2. For Host/Server, enter the NTRIP Caster address.
3. For Port, enter the NTRIP Caster port numbe. This is usually 2101.
4. Click Save.
5. Click Get Mountpoints.
6. Select your mountpoint from the Mountpoint drop down list, being mindful that the distance should not
exceed 50km.
7. Enter your username in the Username box.
8. Enter your password in the Password box.
9. Click Save.
To disconnect from the NTRIP Caster unselect Enabled and click Save.
Troubleshooting NTRIP Caster Connections
If you cannot get the list of mountpoints, ensure the Host Address and Port number are correct for your NTRIP
Caster.
If the Connection Status is not green, and says UNAUTHORISED this indicates an incorrect username or
password.
