Popis: As part of the Space Shuttle return to flight capability, the Russian Segment (RS) Motion Control System (MCS) on the International Space Station (ISS) could be asked to provide attitude control during the Orbiter Repair Maneuver (ORM) for the Thermal Protection System (TPS) repair operation. The MCS may be used as the primary attitude control system, or at least be available as a backup attitude control system in the event of a failure of the United States On-orbit Segment attitude control system for all aspects of the ORM operation. The MCS must provide the capability to damp large attitude rates (as may be encountered after a period of free drift) without allowing the thrusters to adversely interact with the Shuttle Remote Manipulator System (SRMS) and produce excessive motion or brake slippage in SRMS joints. The control strategy is further constrained by large differences in the available thruster control acceleration for the roll channel as compared to the pitch and yaw channels. An integrated solution without changes to the MCS flight software is needed to support the operation. This paper discusses the analyses and control strategies developed to provide ISS attitude control capability during the ORM operation using the RS MCS.
