The European GNSS Service Centre (GSC) is pleased to announce the publication of updated Galileo Satellite Metadata on the GSC web portal. In particular, the update includes metadata for Galileo satellites L9 and L10 and the update of the Mass, Centre of Mass and ANTEX Reference Frame coordinates for all the other satellites.

The Galileo Satellite Metadata section, which can be found under the Support to Developers tab on the GSC site, contains information on satellite properties. This information is necessary in order to properly implement advanced processing algorithms for precise orbit determination or Precise Point Positioning (PPP). This includes physical characteristics, the attitude law and antenna parameters.

As of April 2019, the following Galileo satellite metadata for L9 and L10 (see Satellite Launch Information section) has been added:

  • Mass and Centre of Mass (COM);
  • Antenna Reference Point (ARP);
  • Phase Centre Offsets (PCO) for E1, E5a, E6 and E5b signals; and
  • Laser Retro Reflector Location.


In addition, the Mass, the Centre of Mass (COM) and the ANTEX Reference Frame coordinates for all the other satellites (both IOV and FOC) have been updated as of April 2019.
