TL;DR: In this article, the authors estimate spatial gradients in the ionosphere using the Global Positioning System (GPS) and GLONASS (Russian global navigation system) observations, using data from multiple GPS stations in the vicinity of Murchison Radio-astronomy Observatory (MRO).

TL;DR: In this article, the power spectrum analysis of ionospheric fluctuations in MWA data is presented, where the position offsets of radio sources appearing in two datasets are examined. And the authors show that the position shifts in the positions of celestial sources are proportional to spatial gradients in the electron column density transverse to the line of sight.

TL;DR: The AuScope geodetic Very Long Baseline Interferometry array consists of three new 12 m radio telescopes and a correlation facility in Australia as mentioned in this paper, which will make significant contributions to improving the densification of the International Celestial Reference Frame in the Southern Hemisphere, and subsequently enhance the International Terrestrial Reference Frame through the ability to detect and mitigate systematic error.
