“…The satellite is installed with arms which can change the tether offsets by controlling their endpoints. This implies that the tether tension can not only be used for saving thruster fuel but also for improving the control accuracy of attitude and position of the satellites in the cluster system [41][42][43][44]. The above concept can be used in tethered multi satellites systems for in-orbit servicing by engaging in several missions, for example, recovery, casting, inspection and deorbiting of satellites that are not controlled [45][46][47][48].…”

Space tether satellites systems are one of the most promising directions in the modern space industry. Such systems consist of two or more spacecraft connected to each other by very long tethers. Great extension and variable configuration of the system in the orbital flight conditions provide some dynamic features, which are not typical of conventional spacecraft. The concept of the tethered satellite system (TSS) promises to revolutionize many aspects of space exploration and exploitation. It provides not only numerous possible and valuable applications, but also challenging and interesting problems related to their dynamics, control, and physical implementation. The overarching theme of the paper is to show various control methods of the tethered satellites system (TSS) that have been undertaken recently, and also to emphasize on the importance of the TSS control method as an important aspect in the tether concepts, design, and missions. This review article presents the historical background and recent hot topics for the space tethers, and introduces the dynamics and control of TSSs in a progressive manner, from basic operating principles to the state-of-the-art achievements. The paper introduces the strategies and methods applied in controlling the TSS not excluding their advantages and disadvantages during the tether satellite deployment, retrieval, and station keeping procedures. At the end of the paper, a conclusion is made about the effectiveness of the control methods in stabilizing the libration and vibration motions of the TSS.

“…However, it may not work well for very large and very thin membrane. To make it possible to control the membrane during and after deployment, we consider tethered satellites cluster concept proposed by Matunaga and Mori [7][8][9][10]. This has the following features: 1) multiple satellites, 2) functions of tension force/torque control using tether mechanism, namely, coordinate control of thruster and inner torque, and/or tether and robotic arm, 3) spinning rigidity is used to have system stability, and fuel efficient and shape/position precise controls can be achieved, which is shown by numerical simulations and ground experiments.…”

In this paper, we propose one membrane deployment method: tether-controlled spinning deployment. Very large, thin and flexible membrane (sail) is packed and then is deployed in orbit. In the process of membrane deployment, we use controlled tethers to stably deploy the membrane. Some types of the system are proposed, and the characteristics and technical issues are briefly mentioned. Numerical simulation results using a distributed mass-tether network model show the potential advantage of the proposed method. An experimental set-up of the proposed deployment using the two-dimensional micro-gravity simulators developed at Tokyo Institute of Technology is introduced, and the result of preliminary deployment experiments with a thin membrane of 1m-sized is shown.

“…Berenji et al (1995) performed a simulation of satellite deployment and retrieval based on a mass-less model and a finite element model of a tether. Mori et al (2000) proposed a method to estimate the relative position and attitude (pose) of the satellite based on tether length and tension. Table I compares and contrasts these approaches.…”
