Today’s space technology is continuously developing so that sending satellites into space is not difficult anymore. Besides, satellites have emerged as powerful platforms for telecommunication, survey, and traffic information. For example, many countries have started to develop their satellites. Due to its compact size and uncomplicated system, a cube satellite is suitable as a starting point for the study and development of space technology. This research investigates the stability of a cube satellite with a small size, weighing less than 1 ton and orbiting in a Low-Earth Orbit (LEO) by using the Fundamental Equations of Constrained Motion (FECM) and Sliding-Mode Controller (SMC). The proposed controller guarantees motions of the satellite under the constraint that the satellite has to orbit in a circular trajectory in a Low-Earth Orbit (LEO) and able to handle unexpected changes. The MATLAB program was used to gather data from the numerical simulation. The result from the motion of the analyzing process is rather a remarkable outcome. It may help us to understand the satellite’s movement in a circular orbit with less and adjustable errors. This finding, while preliminary, suggests that we can cope with changes very well particularly the external high-frequency noise. Also, the values of the acceptable errors can be determined by adjusting the control parameters in the proposed controller.
