SSP 41163G, RUSSIAN SEGMENT SPECIFICATION - INTERNATIONAL SPACE STATION PROGRAM (09 OCT 1999)

SSP 41163G, RUSSIAN SEGMENT SPECIFICATION - INTERNATIONAL SPACE STATION PROGRAM (09 OCT 1999)., This specification establishes the performance, design, development, and verification requirements for the Russian Segment of the International Space Station. Requirements in Section 3.2.1 define the performance level of the Russian Segment as a whole. Requirements in Section 3.7 define the performance of the elements which comprise the Russian Segment. These performance requirements are derived from the functional decomposition, a hierarchical breakdown of capabilities and subtiered functions which the Russian Segment will perform. Requirements in Section 3.2.1 are based on the top level capabilities of the functional decomposition and have been grouped into states and modes. Requirements in section 3.7 are based on functions which are subtiered to the parent capabilities defined in 3.2.1. Requirements in Sections 3.2.2 through 3.6 are constraints with which the Russian Segment must comply. The performance requirements herein are applicable during nominal operations, maintenance, or contingency events. This specification is applicable to the Permanent Human Capability (PHC) stage of the International Space Station. Each element level requirement, unless otherwise noted, represents the required performance of the element from the time of its activation, or integration into the Space Station, through to the stage of permanent human capability. This document also identifies incremental performance requirements. Incremental performance requirements are defined as those unique requirements necessary to support the Russian Segment prior to permanent human capability.
