Using NeQuick to reconstruct the 3D electron density of the ionosphere: Benefits and capabilities in single frequency positioning applications

摘要

The term “ionospheric effect” identifies a well known propagation effect, perturbing GNSS signals and ranging observables collected by a navigation receiver. In the case of a single-frequency operating device, the capability of mitigation relies upon the availability of a model for such an effect. This paper aims to demonstrate NeQuick ability of accurately reconstructing the ionospheric behavior at a given date. The ionospheric 3D model is adapted to real situations, starting from experimental input data to determine the “solar effective ionization level maps”: a crucial input information to properly drive NeQuick operation.
