Ionospheric scintillation impact on ambiguity resolution using ADOP in closed form
(2019-08-15)
The Ambiguity Dilution of Precision (ADOP) is a well-known scalar measure that can be used to infer the strength of the Global Navigation Satellite System (GNSS) model of the carrier phase ambiguities involved in precise ...
Interstellar scintillation, ISS, and intrinsic variability of radio AGN
(Elsevier Ltd, 2019)
© 2019We investigate the relationship between the 5 GHz interstellar scintillation (ISS) and the 15 GHz intrinsic variability of the compact, radio-selected active galactic nuclei (AGN) common to the Microarcsecond ...
Temperature and exposure time-dependent scintillation of Eu(III) polyoxometalate under X-ray excitation
(2018-11-01)
Sodium decatungstoeuropate, Na9[Eu(W5O18)2]·14H2O, is a promising material to convert X-ray into visible light. In this work, temperature and exposure time-dependent scintillation of the Na9[Eu(W5O18)2]·14H2O sample under ...
Forecasting the occurrence of ionospheric scintillation activity in the equatorial ionosphere on a day-to-day basis
(Elsevier, 2004-11)
In the low-latitude ionospheric F region, ambient conditions after sunset are often conducive to the generation of small-scale plasma density structures by the Rayleigh–Taylor instability mechanism. Radio wave signals ...
Tackling ionospheric scintillation threat to GNSS in Latin America
(Edp Sciences S A, 2011-01-01)
Scintillations are rapid fluctuations in the phase and amplitude of transionospheric radio signals which are caused by small-scale plasma density irregularities in the ionosphere. In the case of the Global Navigation ...

Towards forecasting and mitigating ionospheric scintillation effects on GNSS
(2007-12-01)
The effect of the ionosphere on the signals of Global Navigation Satellite Systems (GNSS), such as the Global Positionig System (GPS) and the proposed European Galileo, is dependent on the ionospheric electron density, ...

Visual exploration and analysis of ionospheric scintillation monitoring data: The ISMR Query Tool
(2017-07-01)
Ionospheric Scintillations are rapid variations on the phase and/or amplitude of a radio signal as it passes through ionospheric plasma irregularities. The ionosphere is a specific layer of the Earth's atmosphere located ...
