Will.Washington, D.C. :National Aeronautics and Space Administration :[For sale by the Office of Technical Services, Dept. of Commerce],[1971]48 p. :ill. ;26 cm.NASA technical note ;NASA TN D-6449Prepared at Langley Research Center."September 1971."--Cover.Major NASA subject terms: Control simulation, real time operation, space stations, airborne/spaceborne computers, computer programs, control moment gyroscopes, digital computers, systems analysis.Includes bibliographical references (p. 32).A real-time computer-hardware simulation for the investigation of space station dynamics and control problems is described. The simulation utilizes full-scale control moment gyro (CMG) hardware mounted on a moving base simulator, a manual console, and a Control Data (CDC) 6600 digital computer to represent a space station and its control system. The digital computer software is programed in modular form by using separate subroutines or modules to represent the simulated spacecraft, onboard control computer, isolated experiment packages, and other disturbance or dynamics functions associated with space station operation. A complete functional and operational description of the major elements of the space station simulation is included.Mode of access: Internet.Simulation.Space vehicles.Gyroscopes.Computer programs.Langley Research Center.United States.National Aeronautics and Space Administration.01144714120101110103328.020141009010000.020141112165512.02025-01-01T19:23:22Z2025-01-01T18:30:02ZSDR-UIUCUNKNOWNloader.pl-003-020BKsdr-uiuc6403224uiugSDRUIUCuiug.30112106639922UIU6403224UIUUIUC20250101googleuiug.301121066399221971pdbibUS fed doc
