Estimation and analysis of multi-GNSS differential code biases using a hardware signal simulator [PDF]

open access: yes, 2018
In ionospheric modeling, the differential code biases (DCBs) are a non-negligible error source, which are routinely estimated by the different analysis centers of the International GNSS Service (IGS) as a by-product of their global ionospheric analysis ...

Characterization of multi-scale ionospheric irregularities using ground-based and space-based GNSS observations

open access: yesSatellite Navigation, 2021
Ionospheric irregularities can adversely affect the performance of Global Navigation Satellite System (GNSS). However, this opens the possibility of using GNSS as an effective ionospheric remote sensing tool.

Multi-Frequency Precise Point Positioning using GPS and Galileo data with smoothed ionospheric corrections [PDF]

open access: yes, 2018
The poor signal visibility and continuity associated with urban environments together with the slow convergence/reconvergence time of Precise Point Positioning (PPP), usually makes PPP unsuitable for land navigation in cities.
