An investigation on the GNSS ionospheric mapping-functions uncertainties using NeQuick model / R. Ghoddousi-Fard. : M103-3/59-2020E-PDF

"Commonly used two-dimensional ionospheric models for GNSS positioning applications, including Total Electron Content (TEC) maps, require a mapping function (obliquity factor) which is used for conversion between vertical and slant TEC at ionospheric pierce points. In this paper, NeQuick, a three-dimensional semi-empirical model, is used to simulate the level of uncertainties that one may expect from more simplified approaches. In order to evaluate the performance of mapping functions on GNSS vertical TEC estimation, coinciding pierce points from mixed stations and receivers from stations over North America are analyzed. A fit to the NeQuick derived mapping function values resulted in an empirical mapping function which performed slightly better than commonly used mapping functions during the studied periods and locations"--Abstract, page 1.
