Description:
Space weather events related to solar activity can affect
both ground and space-based infrastructures, potentially
resulting in failures or service disruptions across the globe
and causing damage to equipment and systems. Global
Navigation Satellite Systems (GNSS) represent one of such
infrastructures that can suffer from electromagnetic
phenomena in the atmosphere, in particular due to the
interaction of the RF signals with the ionosphere.
The Ionosphere Prediction Service (IPS) is a project funded
by European Commission to provide a prototype platform
for a monitoring and prediction service of potential
ionosphere-related disturbances affecting GNSS user
communities. It is designed to help these communities cope
with the effects of the ionospheric activity and mitigate the
impacts of these effects on the specific GNSS-based
application/service.
The IPS development has been conceived of two
concurrent activities: the design and implementation of the
prototype service and the research activity, which
represents the scientific backbone of IPS and is at the base
of all the models and algorithms used for the computation
of the products.
The products are the basic IPS output that translate the
nowcasting or forecasting information from the whole IPS
system down to the final user. They are fine-tuned to match
the different needs of the communities (scientific, aviation,
high accuracy, etc.) which the service is targeted to and to
warn the GNSS users about possible performance
degradations in the presence of anomalous solar and
atmospheric phenomena. To achieve this overarching aim,
four different blocks of products dealing with solar
activity, ionospheric activity, GNSS receiver and system
performance figures have been developed and integrated
into a unique service chain.
The service is available to a set of invited users since July
2018 through a web portal and its provision with all the
necessary operations will last 6 months. The prototype will
be also ported to the Joint Research Centre (JRC). This
phase will be useful to further test the platform, and to
assess whether and how a dedicated prediction service for
