Products and services for users of real time GNSS applications
Responsible person: René Warnant
Overall description
Nowadays GNSS are widely used to measure positions in the frame of many applications of which the accuracy ranges
from a few mm (Geodesy) to about 10 m (navigation). The influence of the ionosphere on radio signals emitted by
GNSS satellites remains the main limitation to the accuracy and to the reliability of most of these applications.
Indeed, Space Weather can be the origin of disturbed conditions in the ionospheric activity which strongly affects
GNSS applications. Usually, users are not aware about the occurrence of degraded positioning conditions. Therefore,
it is indispensable to monitor GNSS integrity against ionospheric threats and to provide GNSS users with information
ionospheric about ionospheric influence on their applications.
Long Term Goal
To develop operational techniques to assess, to model and to forecast Space Weather effects on real time GNSS
applications.
To develop a web site which provides information about Space Weather activity and about Space Weather effects
on real time GNSS applications.
