Projects and Collaborations
We participate in RAISEARTH, a Horizon Europe project bringing
together European research infrastructures to improve our understanding of the
Sun-Earth environment.
The project provides researchers with access to a wide range of observations,
data services, models and innovative AI-based tools covering the entire Sun-Earth
system. By integrating facilities such as GNSS networks, ionosondes, radars,
magnetometers and space weather models, RAISEARTH helps advance research on
space weather and supports the development of future services that can protect
technologies relying on satellite navigation, communications and space-based systems.
RAISEARTH is funded by the European Union under Horizon Europe Grant
Agreement No. 101289233 from October 2026 to September 2030.
Learn more about the RAISEARTH project.
We participate in GEMOP (Galileo and EGNOS Monitoring of
Performances), a European initiative supporting the independent monitoring of
satellite navigation services and contributing to the assessment of GNSS signal
and service performance.
We monitor GPS Flex Power changes and their impact on GNSS signal reception
worldwide. We also analyse the effects of Solar Radio Bursts, helping to
distinguish solar-induced disruptions from satellite signal variations.
GEMOP is supported by the European Union Agency for the Space Programme
(EUSPA) under Framework Partnership Agreement No. EUSPA/GRANT/03/2021.
We participated in PITHIA-NRF (Plasmasphere Ionosphere
Thermosphere Integrated Research Environment and Access services: a Network of
Research Facilities), a European research infrastructure bringing together
observations, data services and models of the near-Earth space environment.
By integrating facilities such as GNSS networks, ionosondes, radars and satellite
observations, PITHIA-NRF supports research on the ionosphere, thermosphere and
plasmasphere, and helps improve our understanding of space weather and its
impact on technologies such as satellite navigation and communications.
PITHIA-NRF was funded under the European Union's Horizon 2020 Research and
Innovation Programme Grant Agreement No. 101007599 from April 2021 to June 2025.
