Taking into account the quasi-continuous fragmentation of meteor particles, the formulae describing the variation of both light and ionization along the atmospheric trajectory of meteoroids, are derived. Two methods of data processing are presented enabling the determination of the parameters of quasi-continuous fragmentation, [FORMULA], and [FORMULA], characterizing the parent body and the fragmentation products, as well as the bulk density of the parent meteoroid from the light and/or ionization curve. The use of these methods is shown by means of two examples of processing of model curves.
