As of August, 2023, operational Galileo GNSS satellites, with some exceptions, have been updated and are now transmitting an improved I/NAV message.Users will see an enhancement in the Galileo E1 Open Service (OS) performance in terms of robustness and a significant reduction in time to first fix in challenging environments, with both unassisted and assisted GNSS. And, as of October 2018, there are 18 operational Galileo satellites. So satellite coverage isn't the issue. Broadcom strongly believes that a combined GPS + Galileo system will outperform a GPS-only system while not suffering any degradation as a result of the addition of Galileo in receiver designs. The improvement provided by the The Global Positioning System (GPS) was the first global navigation satellite system (GNSS), but has been followed by the three other systems listed in the table (note that BeiDou and Galileo are not fully operational as of 2016). In addition to being globally available systems for positioning and navigation, GNSS systems are widely used as After the fully operational global services of BDS-3 from July 31, 2020, this is the first time to assess the positioning performance of GPS/BDS-3/GLONASS/Galileo in polar regions.
