Abstract As a unique configuration of satellite formation, the tethered satellite system has the advantage for space observation due to its flexible baseline. This paper addresses the concept of a tethered satellite cluster system (TSCS) that consists of a central satellite and several member satellites connected by rope or chain. Using the Clohessey–Whiltshire equation, the orbital coordinate system is set up to describe the motion of the member-satellites, which confirms the initial release velocity near where verifying formations under the nominal control law. The corresponding hardware structure design to achieve this system is also presented in this paper. The working principles and device components of the core structure are then discussed, which simplifies the operating mechanism and enhances the attitude stability. Finally, a ground experiment is implemented using the partial core structure of the TSCS, which illustrates the critical subsystems.
