The results are reported of the very first study of Saturn lightning fine time structure with superfine time resolution (within hundreds to units of nanoseconds). It is ascertained that the lightning time structure has two intrinsic scales: from hundreds/tens to units of microseconds. The analysis was first made of dispersion measure on the Saturn lightning signals’ path from storm in the atmosphere of Saturn to ground-based telescope.

Key words: high time discrimination, lightnings on Saturn, thin temporal pattern, dispersive delay, ionosphere, interplanetary medium
