Real-time interpolation of global ionospheric maps by means of sparse representation
(2021-06-12)
Article
Accés restringit per política de l'editorialIn this paper, we propose a method for the generation of real-time global ionospheric map (RT-GIM) of vertical total electron content (VTEC) from GNSS measurements. The need for interpolation arises from the fact that the ... -
