The fine structure of the absorption spectral lines of the air gas components plays a significant role in the process of the pico- and subpicosecond laser pulses dispersion when they propagate through the atmosphere. It is shown by means of numerical solution of exact wave equation jointly with the media material equations. In particular, the account for the fine structure of lines allows the improvement of the spatial resolution of the optical ranging systems. The results of the numerical simulation of a satellite experimental ranging are presented.
