This guide outlines the key steps for subscribing to SPSLux services and configuring your GNSS receiver. For detailed information on mountpoints, the national coordinate system, and GNSS reference stations, please refer to the relevant sections of this website.
1. SPSLux Service Subscription
Step 1: Create an Account
Register for an SPSLux account at: https://www.spslux.lu/SBC/Account/Register
Please note:
- Your username and password are used to log into your SBC (Spider Business Center) – SPSLux account.
- Your NTRIP username and NTRIP password are used to access the mountpoint stream.
- A valid email address is required to receive updates and maintenance notifications.
Step 2: Complete Registration
- Click the Sign-Up button.
- Confirm your registration via the email you receive.
Step 3: Log In
- Access your account at: http://www.spslux.lu/sbc/ using your SBC-SPSLux credentials.
Step 4: Subscribe to a Service Package
- On your first login, subscribe to the “SPSLux” package via the shop to access all real-time correction services (Network RTK, RTK, and DGNSS).
- To access GNSS raw data from reference stations, please contact us via email at: spslux@act.etat.lu
Step 5: Confirmation
- You will receive an email confirming your subscription.
2. GNSS Rover Configuration
To access SPSLux services via your GNSS receiver, follow these steps:
Step 1: Connect to the SPSLux Server (NTRIP Caster)
Use a mobile internet connection to connect your GNSS receiver to the SPSLux server:
- Server Address:
stream.spslux.lu (Numerical IP: 185.106.24.68) - Port Configuration:
- Port 5005 – for the “SPSLux” package (real-time correction services)
Step 2: Enter Credentials
Input your NTRIP username and NTRIP password as configured during your SPSLux account registration.
Step 3: Verify Connection
If your receiver successfully retrieves the mountpoint list (also known as the source table), the connection to the SPSLux server has been correctly established.
Step 4: SPSLux Mountpoint Selection
Choose a mountpoint from the available list in your GNSS receiver interface. For detailed information on mountpoints, please refer to the relevant section of this website.
Please consider the following when selecting a mountpoint:
- Network RTK Products
Provide network corrections for centimeter-level accuracy.- IMAX and VRS offer equivalent positional accuracy and convergence time.
- Network DGNSS Products
Provide network corrections for sub-meter accuracy (approximately 0.5 meters). - RTK (Single Baseline)
Establishes a connection between the rover and a single reference station. This setup enables up to centimeter-level horizontal accuracy, with performance strongly influenced by the baseline length—the distance between the rover and the reference station. - Satellite System Compatibility
Ensure the selected mountpoint matches the satellite systems supported by your receiver:- GPS (G)
- GLONASS (R)
- GALILEO (E)
- BEIDOU (C)
Step 5: Coordinate system configuration
To compute positions in Luxembourg’s national coordinate reference system LURES LTM, your GNSS rover must be configured with the appropriate transformation and projection parameters. Note that RTCM messages do not include coordinate system information.
- Transformation: ETRF2000 to LUREF
- Projection: Luxembourg Transverse Mercator (LTM)
Further technical details and configuration guidance can be found in the relevant section of this website.
Important Notes
- Reference Station Availability: The current operational status of GNSS reference stations can be viewed under the Site Status section in your SBC-SPSLux account.
- Network Quality Monitoring: Estimated residual ionospheric and tropospheric errors are available via the Nova Maps section in your SBC-SPSLux account.
- Free of Charge: In line with Luxembourg’s open data policy, all real-time and post-processing services are provided free of charge.
- Mobile Access: Users are expected to have a mobile data subscription (e.g., GSM/4G) with a telecom provider to access real-time services.
- Terms of Use: Please review and accept the applicable terms and conditions.
- Troubleshooting: If the connection is unsuccessful, please refer to the Troubleshooting section for guidance. For additional support with the setup and configuration of your rover equipment, please contact your equipment supplier.
