Ionospheric constraints on VHF/UHF communications links during solar maximum and minimum periods
TL;DR: In this article, an extensive VHF/UHF scintillation data base covering the frequency range of VHF to a few gigahertz has been utilized to determine the magnitudes of phase and intensity scintillations and their temporal/spatial structures during the sunspot maximum and minimum periods.
Journal ArticleDOI
Specification and forecasting of scintillations in communication/navigation links: current status and future plans
TL;DR: In this paper, a global specification and forecast system for scintillation is needed in view of our increased reliance on space-based communication and navigation systems, which are vulnerable to ionospheric scintillations.
Journal ArticleDOI
Ionospheric effects of major magnetic storms during the International Space Weather Period of September and October 1999: GPS observations, VHF/UHF scintillations, and in situ density structures at middle and equatorial latitudes

TL;DR: In this article, the ionospheric effects of a halo coronal mass ejection (CME) initiated on the Sun on September 20, 1999, and causing the largest magnetic storm during this month on September 22, 23, and 24, 1999 were studied through their effects on a prototype of a Global Positioning System (GPS)-based navigation system called Wide Area Augmentation System (WAAS) and their impact on global VHF/UHF communication systems.
Journal ArticleDOI
A comparison of TEC fluctuations and scintillations at Ascension Island
TL;DR: In this paper, the authors used amplitude scintillation measurements of L1 (1.575MHz) signals from GPS satellites at Ascension Island (14.45° W, 7.95° S; magnetic latitude 16° S) during February-April, 1998, to compare amplitude scints with fluctuations of the total electron content (TEC).
Journal ArticleDOI
On the coexistence of kilometer- and meter-scale irregularities in the nighttime equatorial F region
TL;DR: In this paper, the relationship between the large-scale irregularities (∼0.1-1 km) giving rise to scintillations and small scale irregularities (3 m) causing 50-MHz backscatter was studied.
