Abstract :
Transionospheric ray tracing through a direct approach to Fermat´s principle is described. Because of the large distances involved in a typical application, non uniform discretisation grids are employed in order to reduce computational requirement. The ray tracing is full 3D and includes geomagnetic effects. Applications such occultation and GPS corrections are discussed.
