iii. Consider the terms and conditions of use.
2. GNSS connection configuration:
a. Connect your GNSS receiver via mobile internet to our server / NTRIP caster:
i. IP: stream.spslux.lu (Numerical IP: 185.106.24.68).
ii. Port:
- 5005 for the package “SPSLux” (Real time correction services).
- 8080 for the package “SPSLux Raw” (Raw GNSS data steam).
b. Enter your NTRIP username and password.
c. If you have access to the mountpoint list / source table, the connection to the SPSLux server has been successfully configured.
3. SPSLux mountpoint selection:
a. Choose a mountpoint from the mountpoint list. Further information can be found here. Please note:
i. Network RTK product: Network corrections for position accuracy of a few centimeters. IMAX and VRS do provide equal positional accuracy and convergence time.
ii. Network DGNSS products: Network corrections for position accuracy of half a meter.
iii. RTK: Single baseline correction to a choosen reference station for horizontal position accuracy of a few centimeters.
iv. Consider which satellite systems (GPS (G), GLONASS (R), GALILEO (E), BEIDOU (C)) your receiver supports. Choose the appropriate mountpoint.
4. Coordinate system configuration:
a. In order to compute positions in the national coordinate reference system LURES LTM, the appropriate transformation and projection has to be implemented within your rover. Further information can be found here.
i. Transformation: ETRF2000toLUREF
ii. Projection: Luxembourg Transverse Mercator projection
Your GNSS receiver should now be ready for use. If your connection fails, please refer to Troubleshooting. For further information regarding the setup and configuration of your rover equipment, please contact your equipment supplier.
