Abstract: An orbital maneuver is an important phase of a space mission. The idea is to change the orbit of a spacecraft, in order to be able to complete the mission goals required. It can be done to insert a spacecraft in its nominal orbit or during the mission to compensate undesired effects of perturbations. To perform the orbital maneuvers, a software that calculates an optimal maneuver is developed. This method will be used as a reference for comparison and analises of the suboptimal methods to be used on board. This method id based on an analytical development that generate equations that can be computed in a shorter time, allowing real time applications. In all the simulations, low thrust is used to make the maneuvers.
