Assessing the benefits of Galileo to high-precision GNSS positioning – RTK, PPP and post-processing
TL;DR: The RTK results show that in challenging environments, the integration of Galileo significantly improves the RTK fix availability and effectively reduces decimeter-to-meter-level position errors caused by incorrect ambiguity fixes, and the post-processing studies show that the inclusion of Galileo provides more accurate solutions for short data durations and long baselines, particularly for data collected under strong multipath conditions.
