WebThe ionosphere can affect a wide range of radio frequency (RF) systems operating below 2 GHz. One option for mitigating these effects is to produce assimilative models of the … WebOne option to improve the TEC mapping is to estimate the 3D ionospheric electron density distribution by tomography or data assimilation based on the dense measuring network of sufficient spatial and temporal resolution and deduce realistic and persistent estimates of the ionospheric effective height [ 24 ].
