TL;DR: This work presents a single-frequency (SF) approach, enabling the joint estimation of VTEC and SDCBs using low-cost receivers, and clarifies how SF approach performs when being applied to GPS L1 data collected by a single receiver under both calm and disturbed ionospheric conditions.

TL;DR: The Modified CCL (MCCL) is capable of excluding the effects of time-varying rDCB from the ionospheric observables, which improves the quality of ionsospheric parameters of interest and has significant potential as a means to detect between-epoch fluctuations experienced by r DCB of a single receiver.

TL;DR: Results show that slant ionospheric delays from RTPPP are more precise and have a much better convergence performance than those from the CCL method in real-time processing.

TL;DR: In this article, the Parkes radio telescope was used to provide archival observations of millisecond pulsars from the radio telescope to help navigate a spacecraft travelling in the solar system.

TL;DR: A series of approaches for GNSS-based ionospheric remote sensing and software has been proposed and developed by the Institute of Geodesy and Geophysics (IGG) in Wuhan as discussed by the authors.
