Bearing Deviation in HF Transionospheric Propagation. II. Applications of Exact Computations

This paper deals with two applications of the exact computations of the ray‐path parameters and in particular, the bearing deviations for an eccentric model ionosphere with no magnetic field derived in a companion paper. These are (a) evaluation of the ITSA three‐dimensional ray‐tracing computer program and (b) investigation of direction‐of‐arrival observations of HF radio waves. In both cases, very good agreement has been found between the two sets of results.
