Corrective Algorithm for Controlling the Thrust Vector of a Spacecraft Propulsion System during Dynamic Operations in Orbit

Abstract: Alongside the maneuvering of spacecraft in the atmosphere, a high intensity of dynamic changes in flight situations also occurs during the active phases of motion of the spacecraft when it is being placed into orbit as an artificial satellite of a planet. Corrective control programs have been developed in the form of functional relationships between control inputs and deviations of trajectory parameters from their nominal values. The use of these programs, combined with calculated analytical dependences, enables the implementation of flight trajectories that are close to optimal disturbed paths, including under conditions of parameter deviations during the atmospheric entry of the spacecraft. © Pleiades Publishing, Ltd. 2025.
