abstract = {Studies have shown that the Brazilian region has several unique features in its geospatial. In this context, the ITASAT-2 mission, plans to launch three satellites in formation flying, in order to improve the knowledge that we have today about the phenomenology of space plasma. The objective is also to capture the signal to provide the geolocation service. This work aims to use simulation and movement control techniques to verify and evaluate the behavior of the following vehicles using different phase angles in detachment and rendezvous maneuvers in relation to the movement of the chief CubeSat considering two orbital disturbances: the 𝑱𝟐 term of the gradient disturbance of gravity due to the inhomogeneity of the Earth and the disturbance due to the differential aerodynamic drag of the satellites. For that, the linear model in Cartesian coordinates called Clohessy-Wiltshire Equations and the optimal control approach described by the Linear Quadratic Regulator (LQR) were used.},
