In this research, the applicability and feasibility of using a spherical-shaped platform as an experimental facility that emulates the dynamics of on-orbit conditions in the laboratory environment is investigated. Indeed, this will permit evaluation of path planning and feedback control algorithms for performing precise satellite maneuvers on an actual system in local situ. The correct operation of this system requires that rolling motion be maintained; nonetheless, some practical issues may occur because of passage to surfaces with different roughnesses, causing an irregular transient performance from a sliding to pure rolling state or vice versa. Noting that an impulse in momentum is verified on reaching the separating limits of those regions, nevertheless the designed attitude controller is observed to be able to reestablish its function despite such disturbances and change of operational conditions. This study is a preliminary step toward final concretization by the build of a prototype in the near future.
