An applied program package for precise calculation of trajectories in the combined electrical and magnetic axial and nonaxial fields. The calculation accurasy is about 1·10-6<\SUP> - 1·10-15<\SUP>. The method based on the techique of approximation by Tchebichev polinimes. Grafic and language software intended for data input, control over computationalprocess and output data visualization is elaborated.
