The first Galileo High Accuracy Service (HAS) Performance Report for Q1 2023, following the HAS Initial Service declaration, is now available at the GSC Electronic Library.

The Q1 2023 Galileo HAS Public Performance Report, provides the status and the achieved performance of the Galileo High Accuracy Service starting from the HAS Initial Service declaration date on January 24 2023.

Starting with this first release, EUSPA will publish public quarterly performance reports to provide users with the latest information on the Galileo HAS measured performance statistics for their Minimum Performance Levels (MPLs), as defined in the applicable Galileo HAS Definition Document HAS-SDD that can be found in the Programme Reference Documents section.

The quarterly report provides information to users on parameters such as the accuracy of delivered HAS Corrections, the availability of HAS Corrections and the availability of HAS Coverage in the intended Service area. All the metrics are evaluated for both dissemination channels, via space (SIS) and terrestrial (IDD) links.

Any MPLs and supplementary metrics provided in this report for the HAS are to be computed over an entire month of collected data. The declaration of HAS Initial Service provision took place on January 24, 2023; thus, the performance parameters for Galileo HAS start as of February 2023.

Highlights from Q1-2023 Public Performance Report:

During the reporting period, the measured HAS performance figures were in line with the MPL targets, specified in the HAS-SDD.
Some highlights from the Q1-2023 performance report:

• Accuracy of the HAS Corrections provided via terrestrial dissemination (IDD) and via SIS for:
  • Orbit was better than or equal to 0.20 [m] for Galileo and  0.23 [m] for GPS satisfying the MPL thresholds (0.20 [m] for Galileo and 0.33 [m] for GPS),
  • Clock offset better than or equal to 0.08 [m] for Galileo and 0.11 [m] for GPS in compliance with the MPL targets (0.12 [m] for Galileo and 0.15 [m] for GPS),
  • Code bias better than or equal to 0.28 [m] for Galileo and 0.34 [m] for GPS. Compliance with the MPL target (threshold is 50 [m] for both Galileo and GPS) achieved with considerable margins.
• Availability of the HAS Corrections provided via terrestrial dissemination and SIS exceeded 93% for Galileo-only corrections (above defined MPL target of 87 %) and not lower than 98% for Galileo + GPS corrections (above defined MPL target of 95 %).
• Coverage of the HAS Service was always 100%, in all the declared Service provision areas.
