WebApr 12, 2024 · Ionospheric effective height (IEH), a key factor affecting ionospheric modeling accuracies by dominating mapping errors, is defined as the single-layer height. From previous studies, the fixed IEH model for a global or local area is unreasonable with respect to the dynamic ionosphere. We present a flexible IEH solution based on neural … WebDec 20, 2024 · The M_GIM software is an application built upon the M_DCB (Jin et al. 2012) software, originally published to the GPS Toolbox for DCB estimation.We extend M_DCB for ionospheric estimation and modeling. M_GIM is modified to be a quad-system ionospheric modeling software based on the original DCB estimation of a GPS-only system with …
Webionospheric delay for the GPS L1 C/A codes’ pseudo-range measurements ranged from about 5 ns (at nighttime) to about 60 ns (at daytime) in February 2014. The ionospheric delay reached 90 ns during a geomagnetic event on MJD 56715 (February 27, 2014).
