Abstract: A tethered control method was studied in order to solve three satellites formation  flying problem. Based on the equilibrium analysis of spinning rigid body satellite, the Thomson and Likins-Pringle equilibrium modeling of three satellites formation flying using tethers were established. The equilibrium conditions were obtained through equilibrium analysis of formation system, and then three control methods were presented to solve disequilibrium problem of Likins-Pringle equilibrium system. Simulation  results demonstrate that the Thomson equilibrium system will be in steady-spin motion with specific conditions, and Likins-Pringle equilibrium system will operate steadily using spring system and tethers added with thrusters control methods under specific conditions.
