Abstract:	The Galileo HAS Initial Service is currently in testing and will be officially declared in the next few months. The HAS SIS ICD is already public and users capable of receiving the E6 signal are starting it signal and decoding the HAS corrections. This paper presents the results of applying the HAS message in several stations worldwide, in order the have a preliminary characterization of the user availability and accuracy. A user PPP solution is calculated in 10 stations (Europe, Africa, America and Asia) for a 6-day period, based on a dual-constellation dual-frequency solution (Galileo E1-E5a, GPS L1C/A-L2C), without integer ambiguity resolution. This work constitutes, to the knowledge of the authors, the first global characterization of the HAS early user performance.
