Revision J xii scope.

This specification establishes the performance and design requirements for the Canadian Mobile Servicing System (MSS), a segment of the International Space Station (ISS). This specification has been developed using SSP 41171, Preparation of Program Unique Specifications (a tailored version of MIL-STD-490), as a guide for a Type A system segment specification.

These performance requirements are derived from the functional decomposition, a hierarchical breakdown of capabilities and subtiered functions which the Space Station and MSS will perform. Requirements in section 3.2.1 are from the ISS System Specification section 3.7.7 and are based on capabilities of the functional decomposition and have been grouped in states and modes.

Section 3.7 requirements are based on the functions which are subtiered to the parent capabilities defined in 3.2.1 and grouped under the major functional elements by the seven MSS functions as defined by the Canadian Space Agency (CSA). Requirements in sections 3.2.2 through 3.6 are constraints with which the MSS must comply. The performance requirements herein are applicable during nominal operations and do not account for maintenance or contingency events. This specification is applicable to the final assembly of the Space Station.

Identification.

This specification is for the MSS, Contract Item # ISSA06A.

System overview.

The purpose of the Canadian provided MSS is to provide external robotic capabilities as a segment of the International ISS. The MSS provides hardware, software, and functions which support external on-orbit Space Station operations of maintenance, inspection, mating, transportation, resupply/ return and external manned operations.

applicable DOCUMENTS Government documents.

Specifications, standards, and handbooks.

The following specifications, standards, and handbooks form a part of this specification to the extent specified herein. For each flight configuration of the Mobile Servicing System, the applicable issues of this specification and the documents referenced herein are defined in jointly agreed National Aeronautics and Space Administration (NASA) or CSA reports as part of the system acceptance and flight readiness processes.
