The most satisfactory way to simulate the low friction aspect of the space environment is by the use of the airbearing technique. This paper presents a design theory of a new spacecraft simulator system installing an airbearing. The 80 cm diameter test table is supported by the 15 cm diameter spherical stainless steel bearing, which is lubricated with compressed air through twelve orifices. As the center of rotation, e. I. the center of the airbearing, can be coincided with the center of gravity of the system by adjusting the balancing weights, the test table can rotate about the spin, pitch and yaw axes with almost negligible friction torque less than 100 mg・cm. Therefore this system is available for studying attitude controls of the sattelite and the control systems. The paper also includes a simple explanation of the structural outline and arrangement of the equipments and the results for the mechanical performance of the facility.
