This user guide leads you through the essential steps of the SPSLux subscription process and GNSS receiver configuration for accessing SPSLux services. More in-depth information on available mountpoints, the national coordinate system and the SPSLux GNSS reference stations can be found in the corresponding sections on this webpage.
1. SPSLux service subscription:
a. Create an SPSLux account on https://www.spslux.lu/SBC/Account/Register . Please consider:
i. Username and password relate to the login for your online SPSLux account.

iii. Please provide a valid e-mail address, as SPSLux updates and scheduled maintenance are communicated to this e- mail address.
b. Hit the Sign-Up button.
c. Confirm your registration via the e-mail you received from firstname.lastname@example.org.
d. Login on http://www.spslux.lu/sbc/ with your SPSLux account username and password. While logging in for the first time, please subscribe to a package:
i. SPSLux package “Surveying” for access to all real time correction services (Network RTK, RTK and DGNSS corrections).
ii. SPSLux package “Raw data” for access to the GNSS data for post-processing (Raw GNSS data stream with Nullantenna).
e. Hit the Subscribe Now button.
f. Your order will be processed by our customer service center and a confirmation e-mail will be sent to you, as soon as the service is ready to be used.
i. In accordance with the Luxemburgish open data policies, real time and post-process services are free of charge.
ii. Regarding mobile distribution (GSM/4G) for SPSLux real time services, it is assumed that the customer has a tele- phone subscription (such as a mobile data subscription) with a telecommunications company.
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: 188.8.131.52).
- 5005 for the SPSLux package “Surveying” (Real time correction services).
- 8080 for the SPSLux package “Raw data” (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:
i. Network RTK: Network corrections for horizontal position accuracy of a few centimeters. Choose either IMAX or VRS. Both correction types provide equal positional accuracy.
ii. DGPS: Network corrections for horizontal position accuracy of half a meter, choose DGPS or DGNSS.
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 get LUREF coordinates in Gauss Luxembourg 1930 format, a transformation and projection to the national coor- dinate system has to be implemented within your rover. Further information can be found here.
i. Transformation: ETRF2000toLUREF .
ii. Projection: Gauss Luxembourg 1930.
Your GNSS receiver should now be ready for use. For troubleshooting please refer to REF Troubleshooting when your connection fails. For further information regarding the setup and configuration of your rover equipment, please contact your equipment supplier.
