In our model, this … Web1 feb. 2024 · Digital ray tracing studies are mainly concerned with two-dimensional tracing that ignores geomagnetic field influences and collision effects (Coleman, 1997, Coleman, 1998, Zhong et al., 2001). If these are to be considered, as well as the non-uniform ionosphere, 3D digital ray tracing must be taken into consideration (Jones, 1968).
WebIONORT uses a three-dimensional electron density specification of the ionosphere, as well as geomagnetic field and neutral particles-electrons collision frequency models having validity in the area of interest. Highlights Software tool for HF radio propagation. HF ray-tracing algorithm useful for wave propagation in the ionospheric plasma. WebRay-tracing is used to examine the accuracy of several well known models for tropospheric delay prediction under varying atmospheric conditions. The models considered include the Hopfield zenith delay model and related mapping functions, the Saastamoinen zenith delay model and mapping function, and three empirical mapping functions based upon the …
