Global ionosphere model with high accuracy and resolution is of great importance for
ionospheric research and global navigation satellite system (GNSS) precise positioning …

The accuracy of ionospheric models estimated by ground‐based multiple global navigation
satellite system ionospheric data over regions with sparse tracking stations is not ideal. To …

Abstract Regional ionospheric Total Electron Content (TEC) models are most significant to
investigate the variability of ionosphere during all-weather conditions. Since the ground …

Abstract The Low‐Earth‐Orbiting (LEO) satellite has a fast motion and thus contributes to
rapid changes in satellite geometric distribution, which can effectively mitigate multipath …

Mapping the ionosphere over low-latitude regions with a high accuracy is a challenging task
due to the complex nature of the ionospheric structure. In this study, the artificial neural …

Daily harmonics of the ionosphere's total electron content (TEC) can be mapped using
Global Navigation Satellite Systems (GNSS), as recently accomplished by Lean and …

NeQuick2 is a three-dimensional ionospheric electron density empirical model that uses
numerical integration to calculate the total electron content along any line-of-sight (LOS). As …

Ionospheric monitoring and modeling have been difficult for a long time over the data-void or
data-sparse oceans. As an emerging remote sensing technique, global navigation satellite …

Navigation technology, which integrates vision, Inertial Measurement Unit (IMU), and Ultra-
Wideband (UWB) sensors in GNSS-denied environments has gained a significant attention …

GNSS single-frequency occultation processing technology has the advantage of simple
instrumentation, but it is not clear about the accuracy of the Beidou-based single-frequency …
