The use of satellite simulators have enhanced in recent years. Each organization anduniversity uses different simulators in order to analyze the performance of AttitudeControl System of satellite. Mostly these simulators work on air-bearing principle.The Department of Computer Science VIII - Aerospace Information Technology atWürzburg University, was assigned the task to design and construct a nano satellitesimulator with 3-axis moving mass actuators to adjust center of mass of satellite.This would in turn cause the tilt of satellite towards excess mass concentration. Itmust be able to fit inside a 30 cm diameter plastic sphere as well as gimbal. Thissphere would be suspended in a spherical air-bearing to visualize the performance ofattitude control algorithm. The physical behavior of the satellite is mathematicallymodeled and control system is devised for the moving mass controller. Several designparameters were evaluated.The proposed design is an octagon satellite structure. The designed structurepresents the ease of access for taking apart the structure and the individual components. The location of each component with respect to center of mass alignment isexpressed. Supporting attachments were specially designed according to the dimensions of each part. The structure contains seven actuating motors three for 3-axismoving mass and four for reaction wheels. Pyramid configuration of the reactionwheels with an inclination of 25is used. Details of the material and its propertiesare discussed. The designed components are locally manufactured and finally assembled within the department. The assembled satellite is tested and conclusion ispresented for future work ; Validerat; 20130509 (global_studentproject_submitter)
