1.0 SCOPE

1.1 PURPOSE

a. Define and control the interfaces which shall be provided by the baseline Shuttle System, for total cargo use by all members of the payload units.

b. Define and control all constraints which shall be observed by all members

of the payload community in using the interfaces so defined. c. Establish commonalty with respect to analytical approaches, analytical

models, technical data and definitions for integrated analyses by all interfacing parties.

1.2 ORGANIZATION OF DOCUMENT

Section 1 (Scope) and Section 2 (Applicable Documents) are standard and self- explanatory. Section 3 (Physical Interfaces) identifies, codes and locates specifically all of the physical interfaces which are defined and controlled by this document. Included is a figure for each of the bulkheads, connector panels, stations, etc., which (1) identifies individual connectors, fittings, etc., (2) locates each dimensionally within the Shuttle Vehicle, and (3) references other paragraphs herein which provide detail performance/design data for each. Sections 4 through 8 define, for each subsystem discipline, detail performance/design data necessary to achieve a satisfactory operational interface. When appropriate, the individual sections establish analytic methodologies for integrated analysis efforts. Where such data is voluminous (i.e., electrical connectors), some tables have been moved to the appendices in the rear of this document. Section 9 (Software Interfaces) defines software detail performance/design data necessary to develop compatible software at the interfaces. Section 10 (Environmental Interfaces) establishes induced environments for which the total cargo must be designed. When appropriate, it also establishes analytic methodologies for integrated analysis efforts. Section 11 (Other Interface Constraints and Limitations) defines general constraints which must be observed in order to ensure satisfactory interface performance and design. Section 12 (Reserved) Section 13 defines the electrical wiring interfaces. Connector interface definitions and pin functions are given for both standard and non-standard cargo interfaces. Section 14 defines the payload deployment and retrieval system. Detail performances and design data necessary to achieve a compatible interface are defined along with the analytical methodology involved. Section 15 refers the user to the sections that cover mandatory requirements imposed upon payload habitable volume.

ERRATA11 ICD-2-19001 1A-2 10-JUN-04

Appendix A (Abbreviations and Acronyms) and Appendix B (Glossary) are self- explanatory. Appendix C lists the Channel Frequency Assignments for transmitting. Appendix E describes the requirements imposed upon payloads when the Extended Duration Orbiter (EDO) pallet is manifested for flights of extended duration. Appendices D, F through H and J through W (Reserved) Appendix I defines the analytical techniques and data to be used to determine the compatibility of payload-induced loads with the Orbiter static limit-load capabilities. Appendix X defines the length selection criteria and deflection data for alternate trunnion lengths.

1.3 EFFECTIVITY

Unless otherwise specified, the interfaces defined and controlled herein are applicable to the operational configuration of the Shuttle System. The Orbiter Vehicle (OV) effectivity sequence is as follows: OV102 and Subs.

1.4 CHANGE POLICY

1.4.1 Scope

All changes to this document shall be controlled in accordance with the procedures prescribed herein and by NSTS 07700, Volume IV. Dispositioned changes shall reflect program decisions and will record new, changed, and/or deleted requirements.

1.4.2 Change Initiation

Payload community PRCB members may initiate changes following NSTS 07700, Volume IV procedures. All other payload community initiated changes shall be submitted to the Space Shuttle Systems Integration Office at the Space Shuttle Program. The Space Shuttle Systems Integration Office shall review the proposed change for technical adequacy, completenes
