Real-Time Ionospheric Scintillation Monitoring
As the millennium approaches we are faced with a period of increasing solar flux and intense ionospheric scintillation. Not only single-frequency, but also dualfrequency GPS measurements will be badly affected by deep scintillation, due to its temporal and spatial decorrelation characteristics. Using the scintillation observables derived from dual-frequency phase and signal-to-noise ratio measu...
متن کاملLatitudinal and temporal variation of equatorial ionospheric irregularities determined from GPS scintillation observations
In this paper we investigate the spatial and temporal distribution of ionospheric irregularities in the South-East Asian longitude sector by analysing the scintillation of GPS signals received at ground based stations. The data used for this work were collected during 1998 to 2002 with our regional network of GPS based scintillation monitors (Thomas et al., 2001). The aim of this analysis is to...
متن کاملA Review of Ionospheric Scintillation Models
This is a general review of the existing climatological models of ionospheric radio scintillation for high and equatorial latitudes. Trans-ionospheric communication of radio waves from transmitter to user is affected by the ionosphere which is highly variable and dynamic in both time and space. Scintillation is the term given to irregular amplitude and phase fluctuations of the received signals...
متن کاملEvaluating GPS Receiver Robustness to Ionospheric Scintillation
Todd E. Humphreys is a research assistant professor in the department of Aerospace Engineering and Engineering Mechanics at the University of Texas at Austin. He will join the faculty of the University of Texas at Austin as an assistant professor in the Fall of 2009. He received a B.S. and M.S. in Electrical and Computer Engineering from Utah State University and his Ph.D. in Aerospace Engineer...
متن کاملEmpirical Characterization and Modeling of GPS Positioning Errors Due to Ionospheric Scintillation
Ionospheric scintillation degrades GPS positioning accuracy in a number of ways. Along each scintillating satellite-receiver link, errors are introduced in the measurements of pseudorange and carrier phase. When the scintillation on a given link is sufficiently intense, the link becomes intermittently unavailable for use in the position solution. The loss of each link leads to an increased dilu...
