In recent years, the development of micro-satellites has received much attention world wide as they are cost effective and require short development cycle. However, attitude control and maneuvering of these micro-satellites using low cost methods represent a challenging problem. The passive methods i.e., gravity gradient, spin stabilization, solar radiation pressure, magnetic torquer etc., may be viable alternative. However, most of these methods have own restrictions and limitations associated with low attitude accuracy. In order to do away with these problems, the present study is undertaken. The system considered here comprises of multiple micro-satellites connected through tether. The system is moving in an inclined non-equatorial orbit. The line-of-sight pointing of multiple micro-satellites is achieved by judiciously changing tether offsets. Lagrangian approach. The open-loop control laws for suitable changes in tether offsets in order to achieve line-of-sight pointing of multiple micro-satellites are developed by linearizing system equation of motion. Then, stability analysis is performed to obtain the conditions for selecting system parameters. Finally, for a detailed assessment of the proposed strategy, the set of exact nonlinear equations of motion is numerically integrated. The effects of various system parameters on system response are then examined. The robustness of the controllers is tested against various conditions. investigated in the present paper. The numerical performance results for the proposed strategy are presented. These results, obtained by numerically integrating nonlinear equations of motion of the system, establish the feasibility of the concept. The concept proposed may be useful for future space mission.
