Estimation of atmospheric parameters for determining dispersion ellipses of space rocket fragments

Abstract

A new approach to the estimation of atmospheric parameters affecting the movement of space rocket fragments in case of accident launches is proposed by the example of the Plesetsk Cosmodrome. Due to the absence of operational information on the vertical distribution of atmospheric parameters above 30 km, the method is considered which allows using available archival aerological data and the statistical characteristics of air density and wind speed components computed from the rocket sounding of the atmosphere for ballistic calculations.
