How to get access to SPSLux services (quick user guide)?

This quick user guide leads you through the essential steps of the subscription process and GNSS receiver configuration for SPSLux services. More in-depth information (available mountpoints, coordinate systems, GNSS reference stations) can be found in the corresponding sections on this webpage.

1.       SPSLux service subscription and connection configuration:

            a.    Create an SPSLux account on

            b.    Connect your GNSS receiver via mobile internet to our server / NTRIP caster:

                    i.      IP: (Numerical IP:

                    ii.     Port 5005 for real time correction services (normal use case). Port 8080 for raw data stream (advanced use case)

            c.     Enter your NTRIP username and password

            d.     If you have access to the mountpoint list (source table), the connection to the SPSLux server has been successfully                     configured.

2.         SPSLux mountpoint selection

            a.    Choose a mountpoint from the mountpoint list

                    i.      For horizontal position accuracy of a few centimeters, choose either IMAX or VRS. Both correction types provide                             equal positional accuracy.

                    ii.      For horizontal position accuracy of half a meter, choose DGPS or DGNSS.

                    iii.     Consider which satellite systems (GPS (G), GLONASS (R), GALILEO (E), BEIDOU (C)) your receiver supports. Choose                                the appropriate mountpoint.

3.         Coordinate system configuration

            a.    In order to get LUREF coordinates, a transformation and projection to the national coordinate system has to be                     implemented within your rover

                    i.      ETRF2000toLUREF transformation

                    ii.     Gauss Luxembourg projection


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.
