Modeling the effects of ionospheric scintillation on GPS/Satellite‐Based Augmentation System availability
Abstract
Ionospheric scintillation is a rapid change in the phase and/or amplitude of a radio signal as it passes through small‐scale plasma density irregularities in the ionosphere. These scintillations not only can reduce the accuracy of GPS/Satellite‐Based Augmentation System (SBAS) receiver pseudorange and carrier phase measurements but also can result in a complete loss of lock on a satellite. In a worst case scenario, loss of lock on enough satellites could result in lost positioning service. Scintillation has not had a major effect on midlatitude regions (e.g., the continental United States) since most severe scintillation occurs in a band approximately 20° on either side of the magnetic equator and to a lesser extent in the polar and auroral regions. Most scintillation occurs for a few hours after sunset during the peak years of the solar cycle. Typical delay locked loop/phase locked loop designs of GPS/SBAS receivers enable them to handle moderate amounts of scintillation. Consequently, any attempt to determine the effects of scintillation on GPS/SBAS must consider both predictions of scintillation activity in the ionosphere and the residual effect of this activity after processing by a receiver. This paper estimates the effects of scintillation on the availability of GPS and SBAS for L1 C/A and L2 semicodeless receivers. These effects are described in terms of loss of lock and degradation of accuracy and are related to different times, ionospheric conditions, and positions o…

Scintillation is more severe in equatorial and high latitude geomagnetic regions, particularly during solar maxima.
“Scintillation effects are more intense in geomagnetic equatorial and high latitude regions where the occurrences are mostly related respectively to the equatorial anomaly and geomagnetic storms.”

In equatorial regions, scintillation occurrence is associated with the equatorial anomaly; in high latitude regions, it is associated with geomagnetic storms.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
