A new modeling approach for on-orbit breakup, named ASSEMBLE (A Semi Stochastic Environment Modeling of Breakup in LEO), was suggested earlier by the authors. Its genesis is on the hypothesis that the orbital parameters at the time of breakup (based on an analysis of the TLE data of some of the fragmentation events), obey certain statistical distributions. The apogee or perigee height and inclination could be described in terms of Laplace distributions and eccentricity by Lognormal distribution. In order to expand the fragmentation scenario to mass, the effective area and the ballistic coefficient some empirical relations available in the literature were utilized in ASSEMBLE. The present paper briefly describes ASSEMBLE followed by its application in simulating some of the historical breakups. In particular the results of the simulations with respect to four major breakups, namely (1) SPOT 1 rocket body on 13 November 1986, (2) COSMOS 1813 on January 29 1987, (3) STEP II rocket body on June3, 1996 and (4) CBERS I/ SAC I on March 11, 2000, are provided. © 2003 by the author(s).
