Visual analytics of time-varying multivariate ionospheric scintillation data
(Computers and Graphics (Pergamon), 2017-11-01) [Artigo]
We present a clustering-based interactive approach to multivariate data analysis, motivated by the specific needs of scintillation data. Ionospheric scintillation is a rapid variation in the amplitude and/or phase of radio ...
Multivariate analysis of combined GPS/GLONASS point positioning performance in Brazilian regions under different ionospheric conditions
(Journal of Atmospheric and Solar-Terrestrial Physics, 2019-06-01) [Artigo]
The development of Global Navigation Satellite Systems (GNSS) was a revolution in activities related to positioning. Currently, GLONASS (Global'naya Navigatsionnaya Sputnikovaya Sistema) and GPS (Global Positioning System) ...
