ASI's new national GNSS frame network has been completed


(22 Nov 2021) Construction of the New National GNSS (Global Navigation Satellite System) Frame Network of the Italian Space Agency (ASI) has been completed. The new network was built by e-GEOS and is set to provide up-to-date, high-precision geodetic information through the signals generated by the satellite navigation systems.

Forty-six stations distributed evenly across the Italian peninsula will enable the acquisition of signals generated by all the global satellite navigation systems, such as the U.S. GPS, the Russian GLONASS, the Chinese Beidou and Europe's Galileo.

ASI's GNSS network, which was designed and developed to provide support for the global geodetic networks (such as the International GNSS Service IGS and the EUropean REference Frame EUREF), will produce data for the management of the International Terrestrial Reference Frame (ITRF).

What's more, it will make a variety of products and services possible: from determining the orbits of GNSS satellites (with an accuracy to the nearest centimetre) to time-synchronising them (better than one nanosecond), useful both for applications on-site as well as to support satellites equipped with GNSS receivers.

The network will enable the provision to the national supply chain - from research centres to SMEs, universities and major corporations - of products and services that are useful for developing high-precision positioning applications, which can be implemented in a wide variety of sectors: from professional applications to those in the field of precision farming.

In order to contribute to scientific activities, some stations in the new GNSS network have been installed in particularly significant locations where purpose-designed structures are already present.

All the data acquired by the "New National GNSS Frame Network" will be received, processed and stored at ASI Space Centre in Matera and provided to all interested users.
