Periodic Reporting for period 2 - NAVSCIN (High Accuracy Navigation under Scintillation Conditions)
Période du rapport: 2020-07-02 au 2021-07-01
The main goal of NAVSCIN has been the development of an improved strategy to mitigate scintillation –a particular type of space weather perturbation– tailored for satellite-based navigation techniques, in close collaboration with users and manufacturers of these technologies. Indeed, once the scintillation effect is correctly detected and mitigated, the availability and accuracy of the five billion devices using Global Navigation Satellite Systems around the world, will dramatically improve. The project has implemented a set of coordinated actions among its different partners that maximize international collaboration between universities, research centres and industry, in different European and Asian countries: First, NAVSCIN has improved the understanding regarding the physical processes resulting in the formation of scintillation, and consequently to identify the drivers in the interplanetary medium, the magnetosphere and the atmosphere. Second, the impact of scintillation on space-based navigation users has been characterised: mainly Ground and Aircraft Based Augmentation Systems (SBAS, GBAS) and high-accuracy navigation techniques (Precise Point Positioning). Third, a set of NAVSCIN algorithms has been developed to support the real-time identification, correction and/or mitigation of scintillation in GNSS receivers. Finally, NAVSCIN has worked systematically with potential users to assess the functionality, reliability and efficiency of the proposed solution, paving the way to its systematic exploitation and to its sustainable operation. Overall, the European competitiveness has been potentiated throughout the project with the exploitation of the research results, ultimately giving highlevel EU employment and maintaining the European status quo of high‐level‐knowledge countries.

We have improved the understanding regarding the physical processes resulting in the formation of scintillation, and consequently to identify the drivers in the interplanetary medium, the magnetosphere and the atmosphere.
NAVSCIN has contributed to tdentify and characterise the impact of scintillation on space-based navigation users: mainly Ground and Aircraft Based Augmentation Systems (SBAS, GBAS) and high-accuracy navigation techniques.
A methodology has been developed suitable to support, for the first time, the real-time identification, correction and/or mitigation of scintillation in GNSS receivers.
Work systematically with potential users to assess the functionality, reliability and efficiency of NAVSCIN proposed solution, paving the way to its systematic exploitation and to its sustainable operation.
