Galileo G1 E5 Quasi-pilot upgrade is completed

Signals transmitted by Galileo satellites in E5 band, when including the G1 E5 QP As announced in the GENERAL NAGU #2025060 and #2026029, 12 Galileo satellites have been reconfigured with the Galileo G1 E5 Quasi-Pilot. The list of satellites and the start date of the Quasi-Pilot signal component transmission is available here.The new Quasi-Pilot signal component enables single-frequency E5 acquisition and improves the service performance. The technical details about the signal are provided in the updated Galileo OS SIS ICD.The E5a-QP, described in the Galileo OS SIS ICD, will not be transmitted by G2G satellites, being superseded by the new QP signals defined in the “Galileo Second Generation Evolution of Quasi-Pilot Signals and Interface Control Information” document. This means that the functionalities and availability of G1 E5 QP signal component will be progressively substituted by the G2 QP signal components, with the launch of G2G satellites and the gradual replacement of current Galileo FOC satellites.The typical availability of the G1 E5 QP signals experienced by the users will be included in the next release of the OS Service Definition Document. More than 4 billion users are already benefitting from Galileo.The Galileo Programme is owned by the EU. Galileo's system design and system evolution are entrusted by EUSPA to ESA.Media note: This feature can be republished without charge provided the European Union Agency for the Space Programme (EUSPA) is acknowledged as the source at the top or the bottom of the story.
