A Review of Space Station ECLSS/ITCS Automation

The on-orbit automation currently planned for the Environmental Control and Life Support System (ECLSS) and the Internal Thermal Control System (ITCS) of the United States on-Orbit Segment (USOS) habitable modules of the International Space Station (ISS) are examined. The discussion includes an overview of the ECLSS, ITCS, and Command and Data Handling (C&DH) system, and features the direct applicability of the planned real-time software control functions to the planned on-orbit ECLSS/ITCS functions.
