摘要: Abstract In the present study, an analytical model of atmospheric entry is calculated using altitude and rate meteor body deceleration in atmosphere from data actual observations. With this purpose strict mathematical algorithm to find basic dynamic parameters theoretical relationship between height velocity that help fit observations along luminous part trajectories best way suggested. The detailed review existing approaches decision problem presented related work by writer [Gritsevich, M.I. Fireballs masses densities: hypotheses reality, in: 37th COSPAR Scientific Assembly, Montreal, Canada, 13–20 July 2008, B04-0041-08, 2008a]. goal study mainly consists qualitative description universal technique for processing flight observational data. main difference previous studies [e.g., Gritsevich, M.I., Stulov, V.P. Entry mass Bolides Canadian Network. Dokl. Akad. Nauk 413, 4, 472–477, 2007a (Phys. (Engl. Transl.) 52, 219–224); Determination Extra-atmospheric Masses Publishing House Faculty Mechanics Mathematics Moscow State University (in Russian), 2007] given are approximated solution fundamental differential equations physics. As today method allows determine bodies with high accuracy estimate.
