Abstract
The results concerning the modelling of the propagation of radio waves transmitted by GPS satellites in the presence of sporadic E layers are described. The greatest deviations of the difference between the true path and the geometrical path found for the higher frequency from the difference true path-geometrical path obtained for the lower frequency attain values of the order of 26 cm at the zenith angle 75° of the satellite in the N-S direction (summer, night and low solar activity conditions) and about 7 cm in the W-E direction (summer and winter night, as well as low solar activity conditions).
