The aim of the study is to determine the required maneuvers to control geostationary satellites within a delimited control window. It will be done defining different strategies of control for the calculation of impulsive maneuvers to obtain optimal values which will minimize the fuel consumption and will provide an automatic control for any situation. For each implemented strategy, an algorithm will be developed. These algorithms will be applied to some relevant longitudes in order to prove that they could be used for any longitude yielding good results. The geostationary control will only implement in-plane maneuvers (East/West). This means that only the longitude and the radial direction will be controlled, ignoring changes in inclination.
