Mid-latitude ionospheric scintillation anomaly in the Far East [PDF]
A long-term (over 3 years) study has been undertaken to obtain a comprehensive evaluation of VHF ionospheric scintillation morphology in East Asia (at Kokobunji in Japan), using amplitude records from Transit satellites.

Analysis of Ionospheric Scintillations using Wideband GPS L1 C/A Signal Data [PDF]
A non-real-time GPS receiver has been developed and tested for use in scintillation analysis. The receiver consists of a digital storage receiver and non-real-time software acquisition and tracking algorithms.

Purpose: Variations of ionospheric scintillation index of the power cosmic radio sources (3С144, 3С274, 3С405, and 3С461) observed for the year-to-day time intervals with the radio telescope at the decameter wavelengths are analyzed.

Systematic and Stochastic Variations in Pulsar Dispersion Measures [PDF]
We analyze deterministic and random temporal variations in dispersion measure (DM) from the full three-dimensional velocities of pulsars with respect to the solar system, combined with electron-density variations on a wide range of length scales ...

Broadband Meter-Wavelength Observations of Ionospheric Scintillation
Intensity scintillations of cosmic radio sources are used to study astrophysical plasmas like the ionosphere, the solar wind, and the interstellar medium. Normally these observations are relatively narrow band. With Low Frequency Array (LOFAR) technology

Multi-frequency GNSS robust carrier tracking for ionospheric scintillation mitigation
Ionospheric scintillation is the physical phenomena affecting radio waves propagating from the space through the ionosphere to earth. The signal distortion induced by scintillation can pose a major threat to some GNSS application. Scintillation is one of
