“…For simplicity and focusing attention on the effects of separation strategy on the deployment, the tethers are considered as massless and straight. Additionally, some sensible assumptions are made for the same purpose: (1) the center of mass of the system moves on a Keplerian orbit, (2) the perturbations such as atmospheric drag and Earth oblateness, are negligible, and (3) the eccentricity of the orbit is small and would not induce the system into chaos motion [19]. The dynamic behavior of the multitethered satellite system is depicted with respect to the orbital frame with its origin at the center of mass of the system, as shown in Figure 1.…”

This paper investigates the effects of separation strategy and parameters related to deployment on the dynamic behavior of multitethered chain-type satellite system. The system, including several satellites connected by tethers which are considered as massless and straight, is modeled as an extension of a two-body dumbbell tethered system. The dynamic equations of system in absence of perturbations and external disturbances are derived using Newtonian Method. To observe the effect of deployment rate on the motion of system, a parametric analysis of the deployment of a three-body tethered system with different deployment rates is carried out. Moreover, a four-body tethered system is used to investigate the effect of separation strategies on the dynamic behavior of system during the deployment phase. The numerical results suggest that the system with simultaneous separation costs less time to complete the deployment. If the ratio of deployment rates is in consistence with that of their desired lengths, the tethers deployed simultaneously would have a synchronous motion. It is also observed that the system employing separation bolt has a better performance than the system separated by spring mechanism since the larger separation velocity which is not along local vertical may cause a rotation.

“…Then the length of unstretched tether is fixed. If the tether length is bigger than the fixed value, the tether tension arises and could be approximately expressed as (19). Otherwise, the tether is slack and the tether tension does not exist.…”

“…The testbed utilizes an Air-Bearing Inclinable Turntable or A-BIT, whose inclination and rotation rate can be adjusted independently. A similar experimental technique was employed by [5] [6], focusing on the dynamics of a climber attached to a pre-deployed tether. The A-BIT aims to provide insight into the libration dynamics of a tethered satellite and provide a platform to test control strategies that stabilize the libration of the tethered satellite system.…”

This paper discusses the development of a ground based experimental environment that can mimic the libration dynamics of tethered satellite systems. The setup consists of an Air-Bearing Inclinable Turntable (A-BIT), whose inclination and rotation rate can be adjusted independently. Appropriate scaling factors help compare the tethered system in the experiment to that in orbit, both of which experience vastly different magnitudes of forces. The two scenarios also differ in their physical parameters including the length of the tether, the mass of the satellite, and the tension along the tether. The scaling factors are used to compare the behavior of these two tethered satellite systems.
