The controlled motion of an aerospace shuttle descending through the atmosphere is analyzed by using a mathematical modeling. The shuttle model includes a bank of aerodynamic characteristics, geometry, parameters of the reaction control system and aerodynamic control surfaces, algorithms of the control system, etc. The model of perturbed atmosphere describes the environment. In numerical integration of the motion equations certain difficulties arise because of discontinuities in the right hand side due to the switch on of orientation engines as well as small step of integration (0.03 to 0.05 s) and long time of descent through the atmosphere (1800 to 2000 s). Methods of increasing the accuracy of calculations by improving the models and computational techniques used are discussed.
