             abstract = "A major motivation for the development of this study is the 
                         ITASAT-2 mission of the Aeronautics Institute of Technology, whose 
                         one of the main objectives is to be able to geolocate an 
                         electromagnetic emitting source on the Earth's surface. For this, 
                         the mission will have a formation flying of three CubeSats. The 
                         topology and configuration must be chosen such that the 
                         geolocation system presents the necessary precision, while the 
                         other objectives of the mission are fulfilled. Thus, this study 
                         intends to simulate various topologies by using the dynamics of 
                         orbital motion and a geolocation algorithm based on combined 
                         measurements of TDOA and FDOA. It is expected to obtain a base of 
                         results that will assist the development team of the ITASAT-2 
                         mission and related missions in choosing the best topology and 
                         configurations for the formation flying. Therefore, this study 
                         proves to be important as it demonstrates great potential of 
                         contributions to the scientific and technical community of the 
                         aerospace area. This scenario, therefore, serves as a motivation 
                         for the development of the study presented here, which is also 
                         based on the current development of the ITASAT-2 mission, by the 
                         Technological Institute of Aeronautics (ITA) in collaboration, in 
                         terms of research, with the National Institute of Space Research 
                         (INPE) and researchers from Brazilian public universities. The 
                         ITASAT-2 mission is designed to be composed of a formation flying 
                         of three identical CubeSats 8U or even 12U. The main objectives of 
                         the mission are: to conduct scientific and technological 
                         investigations around the appearance and growth of irregularities 
                         in the plasma structure of the ionosphere; and propose a specific 
                         formation flying for the CubeSats so that they are able to locate 
                         an electromagnetic emitting source on the Earth's surface. To 
                         achieve the necessary requirements of the ITASAT-2 mission, it is 
                         necessary to evaluate the possible topologies and configurations 
                         for the formation that enable, at the same time, the study of the 
                         space climate and the geolocation process.",
