The last Open Service Quarterly Performance Report of 2017 (from October to December) has been published in the Performance Reports section of the GSC web portal.
The fourth OS Performance Report is available in the Electronic Library, Galileo Initial Open Service performance figures exceed Minimum Performance Level targets in Q4 providing the status of the Galileo constellation and the achieved performance over the reporting period (October, November and December 2017).
These quarterly reports provide the public with the latest information on the Galileo Open Service measured performance statistics with respect to their Minimum Performance Levels (MPLs), as declared in the Galileo OS Service Definition Document (OS SDD), in particular, on parameters such as:
- Galileo Initial OS ranging performance,
- Galileo Coordinated Universal Time (UTC) dissemination,
- Galileo to GPS Time Offset (GGTO) determination performance, and
- Timely publication of NAGUs (Notice Advisory to Galileo Users).
Highlights from Q4 2017
As in the preceding three quarters of 2017, the measured Galileo Initial Open Service performance figures generally exceed the MPL targets by significant margins.
Some highlights from the Q4 performance report:
- Availability of both the Galileo Ranging Service at the Worst User Location (WUL) and Healthy Signal has been significantly better than expected: both have achieved values above the threshold (which is 87%).
- Availability of the Galileo UTC Determination and the GGTO Determination Services were achieved, with all monthly values above MPL targets (in particular, 100% in November and December);
- MPLs of the Timely Publication of NAGUs were met during the whole period for both Planned and Unplanned events: target of at least 24 hours before the start of a scheduled event is always achieved, as well as not more than 72 hours after an unscheduled one.
