Abstract : A computer program has been developed for the implementation of a three-dimensional predictive model for high-frequency ionospheric propagation effects. This program has been employed for the rapid calculation of path deviation effects arising from large-scale temporal and geographic variations in the ionospheric structure. The characteristics and capabilities of this computer program are descrived in detail and an example of its use is provided. (Author)
