A Method for Determining Parameters of Mid-Scale Traveling Ionospheric Disturbances [PDF]

Sensors
The growing amount of available experimental data on the Earth’s ionosphere total electron content measurements requires the development of modern data processing instruments. Traveling ionospheric disturbances (TIDs) are one of the ionospheric phenomena

Ionosphere-weighted undifferenced and uncombined PPP-RTK: theoretical models and experimental results

GPS Solutions, 2021
Precise ionospheric information, as like precise satellite orbits, clocks, and code/phase biases, is a critical factor for achieving fast integer ambiguity resolution in precise point positioning (PPP-AR).

Saturn’s Ionosphere [PDF]

, 2018
This chapter summarizes our current understanding of the ionosphere of Saturn. We give an overview of Saturn ionospheric science from the Voyager era to the present, with a focus on the wealth of new data and discoveries enabled by Cassini, including a massive increase in the number of electron density altitude profiles.

Comparison of travelling ionospheric disturbance measurements with thermosphere/ionosphere model results [PDF]

Annales Geophysicae, 2003
Comparisons of modeled and measured responses of the ionosphere to the passage of atmospheric gravity waves are made for data recorded by an ionosonde located at Almaty (76°55' E, 43°15' N) from June 2000 until May 2001.

Characterization of the ionosphere above the Murchison Radio Observatory using the Murchison Widefield Array [PDF]

, 2017
We detail new techniques for analysing ionospheric activity, using Epoch of Reionisation (EoR) datasets obtained with the Murchison Widefield Array (MWA), calibrated by the `Real-Time System' (RTS).
