             abstract = "In this work the problem of orbital maintenance of a symmetrical 
                         constellation of satellites, with minimum fuel consumption, is 
                         studied using bi-impulsive maneuvers with time constraint. When 
                         all the satellites are considered it is almost impossible to 
                         determine the optimal maneuver strategy that minimizes the fuel 
                         consumption. Therefore, the goal of this work is to formulate and 
                         to study maneuver strategies that make possible to obtain 
                         solutions with small fuel consumption considering all the 
                         satellites in the constellation. The problem can be formulated as 
                         a multi-objective problem due to the nature of the station-keeping 
                         of a satellite constellation. Thus, the multi-objective problem 
                         was defined and a new multi-objective optimization method was 
                         applied. This method can consider n conflicting objectives 
                         simultaneously without reducing the problem to an optimization of 
                         only one objective, as occurs with most of the methods found in 
                         the literature. This method, called the Smallest Loss Criterion, 
                         was presented in Rocco et al. (2003). It was compared with other 
                         existent methods and it was verified that it may supply better 
                         results to the problem of the station-keeping of satellite 
                         constellations. In this work, some applications of the Smallest 
                         Loss Criterion, presented in Rocco et al. (2003) and Rocco et al. 
                         (2005), are reproduced considering now that the satellite 
                         positions are determined using GPS measures and that there are 
                         errors in the magnitude and direction of the impulses applied in 
                         the orbital maneuvers. So, these measures of the satellite 
                         positions contain uncertainties that are filtered by a Kalman 
                         filter.",
