GLOBAL POSITIONING SYSTEM STUDIES OF EQUATORIAL SCINTILLATIONS [PDF]
The Global Positioning System (GPS) satellites provide an extensive array of beacon signals for probing the ionosphere. Studies of ionospheric propagation at the GPS L band frequencies (1.2 and 1.6 Hz) are of great interest for proposed communications ...

Polarization-resolved scintillations in Young's experiment
The conventional scintillation, or intensity fluctuation, that occurs in random electromagnetic beams is just one member of a broader class of four interconnected, polarization-resolved scintillations.

Characteristics of VHF radiowave scintillations over a solar cycle (1983−1993) at a low-latitude station: Waltair (17.7°N, 83.3°E) [PDF]
The characteristics of VHF radiowave scintillations at 244 MHz (FLEETSAT) during a complete solar cycle (1983–93) at a low-latitude station, Waltair (17.7°N, 83.3°E), are presented.

Influence of different types of ionospheric disturbances on GPS signals at polar latitudes [PDF]
The comparative research of the influence of different types of auroral particle precipitation and polar cap patches (PCPs) on the global positioning system (GPS) signals disturbances in the polar ionosphere was done.

VARIABLE RADIO SOURCES AND TAKING INTO ACCOUNT OF IONOSPHERIC EFFECTS
Histograms and mean value of scintillations indexes are obtained for power cosmic radio sources on observations during 1998-2001. Using simulations it is showed that scintillations with periods more then 10 minutes give the error of measuring of ...

Effect of scintillations arises in the result of interaction of radio signal from the cosmic radio source with irregularities of ionosphere plasma which appears at the registration of observations as amplitude fluctuations.

Simultaneous observations of ESF irregularities over Indian region using radar and GPS [PDF]
In this paper, we present simultaneous observations of temporal and spatial variability of total electron content (TEC) and GPS amplitude scintillations on L1 frequency (1.575 GHz) during the time of equatorial spread F (ESF) while the MST radar (53 ...

SPACE WEATHER: RISK FACTORS FOR GLOBAL NAVIGATION SATELLITE SYSTEMS
Extreme space weather events affect the stability and quality of the global navigation satellite systems (GNSS) of the second generation (GPS, GLONASS, Galileo, BeiDou/Compass) and GNSS augmentation.

SibNet — Siberian Global Navigation Satellite System Network: Current state
In 2011, ISTP SB RAS began to deploy a routinely operating network of receivers of global navigation satellite system signals. To date, eight permanent and one temporal sites in the Siberian region are operating on a regular basis.

Cosmic-Ray Scintillations [PDF]
This Thesis reports the observation and theoretical interpretation of a new physical phenomenon. Cosmic-ray "scintillations" are temporal fluctuations in the counting rate of a detector pointing in a fixed direction in space.
