Low-thrust guidance and control of satellite Formation Flying relative motion is a field of study that is gaining more and more attention by researchers from every part of the world due to the recent development of more and more performing electric propulsion systems and since future missions will follow the trend of miniaturizing spacecraft. The challenge is to design a controller that must address limited thrusting and propellant capabilities while maintaining operational aspects, such as collision safety and time constraints. For the scope of this work, a formation of satellites in LEO is considered, employing thrusters capable of providing thrust in the order of µ-Newtons.
