A spacecraft motion simulation device provides up to four degrees of freedom of motion to a test article and enables viewing a picture on a projection screen from a camera within the test article. One or more of such pictures may be moved during the test and the test article may be thus also moved in accordance with the testing of controls thereon. Closed loop control of the test article may be achieved using attitude control circuits for adjusting test article position and attitude relative to recognized elements within the projected screens.
