How to get access to SPSLux services?

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 via . Please consider:

                    i.       Username and password relate to the login for your SBC (Spider Business Center)-SPSLux account.

                    ii.      NTRIP username and NTRIP password relate to the login for the mountpoint stream.

                    iii.     Please provide a valid e-mail address, as information on 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

            d.     Login on with your SBC-SPSLux account username and password. While logging in for the first time, please subscribe to at least one package:

                     i.       Package "SPSLux" for access to all real time correction services (Network RTK, RTK and DGNSS).

                     ii.      Package “SPSLux Raw” grants access to GNSS raw data of the reference stations Nullantenna).

            e.      Hit the Subscribe 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.

            g.       Note:

                     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: (Numerical IP:

                     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.
