Ionosphere irregularity
WebAbstract: The ionosphere, as the largest and least predictable error source, its behavior cannot be observed at all places simultaneously. The confidence bound, called the grid … Web12 dec. 2014 · The ionosphere plays an important role in GNSS applications because it influences radio wave propagation. The ionospheric delay is the biggest error source for satellite navigation signals, but it can be directly measured and mitigated using dual-frequency GNSS receivers.

Webionosphere as a dynamical system with signatures of complexity. The system is robust in its overall configuration, with smooth space-time patterns of daily, seasonal and Solar Cycle variability, but shows a hierarchy of interactions among its sub-systems, yielding apparent unpredictability, space-time irregularity, and turbulence.

WebA field-aligned irregularity ( FAI) is an anisotropic (different values when measured in different directions) perturbation of plasma density associated with magnetic fields. FAIs are often thought of in the context of the Earth's ionosphere where several natural processes generate FAIs in the E-region and F-region. [1]
