Abstract
Abstract. The ESA MONITOR network is composed of high-frequency-sampling global navigation satellite systems (GNSS) receivers deployed mainly at low and high latitudes to study ionosphere variability and jointly with global GNSS data and ionospheric processing software in support of the GNSS and its satellite-based augmentation systems (SBAS) like the European EGNOS. In a recent phase of the project, the network was merged with the CNES/ASECNA network and new receivers were added to complement the latter in the western African sector. This paper summarizes MONITOR, presenting two case studies on scintillations (using almost 2 years of data measurements). The first case occurred during the major St. Patrick's Day geomagnetic storm in 2015. The second case study was performed in the last phase of the project, which was supported by ESA EGNOS Project Office, when we paid special attention to extreme events that might degrade the system performance of the European EGNOS.
Highlights
MONITOR (MONitoring of Ionosphere by innovative Techniques coordinated Observations and Resources) (Béniguel et al, 2015) is a project conducted by the European Space Agency’s global navigation satellite systems (GNSS) Evolution Programme
It is dedicated to the collection, processing, and archiving of ionospheric data and products during active periods of solar activity; the development of improved scintillation monitoring instrumentation; and the establishment of a scintillation monitoring network in order to build the appropriate infrastructure for analysing the impact of the ionosphere on European GNSS (EGNOS and Galileo) system performance
The receivers deployed for the project have been installed both in low and high latitudes, which are the two main regions where the ionosphere might be the cause of EGNOS decreases in performance
Summary
MONITOR (MONitoring of Ionosphere by innovative Techniques coordinated Observations and Resources) (Béniguel et al, 2015) is a project conducted by the European Space Agency’s GNSS Evolution Programme. The ionosphere MONITOR stations (IMONIS) are equipped with a 50 Hz scintillation receiver (Septentrio PolaRxS or NovAtel 4004B) and bit grabbers in order to record IF data beyond the tracking capability of GNSS receivers for Published by Copernicus Publications on behalf of the European Geosciences Union. The stations in western Africa were deployed to complement the five stations of the CNES/ASECNA SAGAIE network (Stations ASECNA GNSS pour l’Analyse de l’Ionosphère Equatoriale) (Secrétan et al, 2014). Patrick’s Day magnetic storm of March 2015, which is the most important storm to occur so far during this 24th solar cycle
