Description du projet
Atténuer les perturbations dues à la scintillation dans les systèmes mondiaux de navigation par satellite
Un phénomène connu sous le nom de scintillation se produit dans certaines conditions ionosphériques, perturbant les signaux radio des systèmes mondiaux de navigation par satellite (GNSS). Ce phénomène est responsable de problèmes temporaires de positionnement et de synchronisation des services mondial de positionnement (GPS), qui peuvent se révéler onéreux pour certains utilisateurs. Le projet NAVSCIN, financé par le CSMA,entend élaborer une stratégie permettant d’atténuer le problème des interférences radio causées par la scintillation. Il commencera par analyser de manière systématique l’incidence de la scintillation afin d’identifier les processus qui la déclenchent. Le projet quantifiera ensuite l’impact de la scintillation sur les systèmes GNSS spatiaux et concevra des algorithmes appropriés permettant de détecter, de corriger ou d’atténuer les perturbations des transmissions GNSS.
Objectif
The main goal of NAVSCIN is to develop 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 implements 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 will improve 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 will be characterised: mainly Ground and Aircraft Based Augmentation Systems (SBAS, GBAS) and high-accuracy navigation techniques (Precise Point Positioning). Third, a set of NAVSCIN algorithms will be developed suitable to support, for the first time, the real-time identification, correction and/or mitigation of scintillation in GNSS receivers. Finally, NAVSCIN will work 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 will be potentiated throughout the project with the exploitation of the research results, ultimately giving high-level EU employment and maintaining the European status quo of high‐level‐knowledge countries.
