Project description
Mitigating scintillation disruptions in global navigation satellite systems
Under certain ionospheric conditions, a phenomenon known as scintillation occurs, disrupting the radio signals of global navigation satellite systems (GNSS). This causes temporary positioning and timing glitches in global positioning services that can be costly for some users. The MSCA-funded NAVSCIN project aims to devise a strategy to alleviate the issue of radio interference caused by scintillation. It will first systematically analyse the incidence of scintillation to identify the processes that trigger it. The project will then quantify the impact of scintillation on space-based GNSS systems and design appropriate algorithms that can detect, correct or mitigate disruptions in GNSS transmissions.
Objective
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.
