WebJan 1, 2024 · 1. The ionosphere. The Earth's ionosphere is the atmospheric region above about 60 km in which a high number of neutral particles are ionized by ultraviolet and X solar photons in the wavelength at and lower than 121 nm generating a plasma.The presence of free electrons in this region is of primary importance for the propagation of radio waves … Webof multi-GNSS DCB estimation is proposed without relying on the ionospheric function model and existing global ionosphere map (GIM). In the following, the proposed new method is described in detail in Section 2. In Section 3, 200 days of observations from more than 300 multi-GNSS experiment (MGEX) stations are collected for the estimation of the
