Welcome to MONITOR Project - The European Ionospheric Network
The activity MONITOR, "Ionospheric Monitoring Experimentation Plan & Instrument Development" funded by the ESA's GNSS Evolutions Programme has been initiated in 2010.
The main goal is to understand and consolidate the knowledge related to the impact of ionospheric effects on the performance of GNSS (in particular, EGNOS and Galileo) systems, in particular those effects happening during extreme events around solar maximum.
In order to achieve this goal, the following objectives were identified:
- design and implementation of an experiment to gather relevant data during active years of next solar cycle, including external data providers from various ground-based and space-based instruments, and the installation of ground stations for specific investigations. Those stations include off-the-shelf ground ionospheric measurement equipment (mainly composed by GPS geodetic receivers adapted for ionospheric measurements). Furthermore, some of the stations will include newly developed instruments based on Galileo signals (see 3 below);
- design and development of a central archiving and processing facility for storing all data (from external providers and project stations) and deriving/presenting results and final products;
- design and development of a ground-based GNSS ionospheric instrument based on a modified Galileo software receiver able to use Galileo signal-in-space
- analysis of data (short-term disturbances, long-term statistics) and synthesis into models. Synthesis of conclusions and recommendations related to effects into GNSS performance and development of mitigation techniques.
