RESUMO

This work considers the coupling between attitude and orbit control used during an orbital transference which uses a continuous propulsive system capable impulse for a long time. The dynamic equations of movement are used to propagate the orbit and attitude states. It is studied some cases which comes from the effect of control during the orbital transference. It is considered a closed-loop control system and high specific impulse low propulsion. It isnt of interest in this work to specify what kind of disturbances and/or perturbations, and neither to choose what continuous propulsion system must be used. Simulations are used to study the orbit deviation and to evaluate the control system. The system must be modularized in order to test the control strategies separately and coupled. It is studied different cases under different conditions. The results had shown that the continuous impulse of propulsion offer advantages for some spatial missions. It was confirmed the closed-loop control to the orbit control is necessary.
