The Navigation Support Office records GNSS station data and generates GNSS products for all constellations (GPS, Galileo, Glonass, Beidou, QZSS) on an operational basis. All products are characterized by high precision, availability and reliability. In the following the RINEX codes are used to identify the systems: Galileo (E), GPS (G), Glonass (R), Beidou (C), QZSS (J).

This page gives an overview on our published data and products.

Detailed information concerning the processing strategy and models adopted for the products generation are available in our Analysis Strategy Summaries for IGS and ESOC MGNSS.

Standard Products and Data

Our latest published products are freely available on our web page ( http://navigation-office.esa.int/products/gnss-products/ ) and can be retrieved via file browser or http download methods (e.g. wget or curl) .

GNSS station data (RINEX) and historical products can be found on ESA's GNSS Science Archive and Service Centre ( GSSC ).

IMPORTANT: please check regularly our Important Notices and Announcements page, to stay up to date with our latest upgrades and changes.
