- Abstract
In this work the problem of the maintenance of a satellites constellation using hyperbolic orbital transfers between coplanar orbits, with minimum fuel consumption but with time limit for this transfer is considered. This problem can be defined as a multi-objective problem because in the orbital maintenance many parameters must be considered to determine the maneuvers to be applied. It can be desired to minimize simultaneously, the fuel consumption, the time spent in the maneuvers and the positioning error. However, those objectives, generally, are conflicting. When one of them is optimized the others, are not, necessarily. Other parameters beyond those can be considered, turning the problem even more complex. If the n satellites of the constellation will be considered, must be taken into account the problem of simultaneous optimization of the maneuvers for the n satellites. In this case, it is practically impossible to determine the optimal solution that minimizes all the objectives simultaneously. Therefore, in this work the multi-objective optimization methodology presented in Rocco et al. (2003) was used to define a maneuver strategy to be applied in a satellite constellation, in way to reduce the fuel consumption, the time spent in the maneuvers and the positioning error for the entire constellation.
