Overview
SPSLux (Satellite Positioning System Luxembourg) is the national satellite positioning service managed by the Luxembourg Cadastre and Mapping Agency. Operated by the Geodetic Department, SPSLux provides high-precision positioning data free of charge.
The system enables users to determine their position with centimeter-level accuracy, serving as a fundamental reference for both horizontal and vertical positioning. SPSLux supports a wide range of critical applications, including:
- Cartography and geospatial data collection
- Land boundary surveying and land administration
- Precision agriculture
- Construction and infrastructure development
- Security and public safety
- Urban planning and environmental monitoring
Services Provided
Real-Time Services
SPSLux offers real-time correction data via internet, supporting:
- Network RTK (Real-Time Kinematic)
- RTK
- DGNSS (Differential GNSS)
These corrections allow GNSS receivers to compute positions in real time at a frequency of 1 Hz. Under good conditions and with professional use, (N)RTK-based services provide a horizontal positional accuracy (σ) of approximately 2–3 cm and a vertical accuracy (σ) of approximately 3–5 cm. DGNSS, by comparison, achieves a positional accuracy of around 0.5 meters.
Post-Processing Services
SPSLux also provides GNSS observation data in RINEX format from continuously operating reference stations. These files are typically available within 24 hours and support post-processing applications that can achieve millimeter-level accuracy.
