The European GNSS Service Centre (GSC) is pleased to announce the publication of the updated GALILEO ANTEX file in the Metadata section of the GSC web portal.

The Galileo ANTEX file includes the Phase Centre Variation (PCV), which is the variation of the electrical phase centre of the antenna with respect to the mean phase centre for a given direction.

This file has now been updated to include the Direction-Dependant PCV figures for L9 and L10 Galileo satellites (see Satellite Launch Information section). The updated ANTEX file can be found here.

It takes several months to generate the ANTEX file. The process is not straightforward, as it requires performing complex measurements, as well as thorough post-processing and validation of the obtained data.

Galileo Satellite Metadata

The Galileo Satellite Metadata section (under the Support to Developers tab on the GSC site) contains information about the satellite properties, which is needed to properly implement advanced processing algorithms for precise orbit determination or Precise Point Positioning (PPP).

For further up-to-date information on the Galileo system and its services, visit the European GNSS Service Centre (GSC) website, and the GSC Help Desk is available for any comments or questions related to Galileo.
