DESCRIPTION PUB DATE Basic Initial issue 05/2010 A Revised to add definition to the interface by removing TBDs and 07/2010 providing updates based on matured design. Sections 4 and 5 were swapped, including Section 6 and Section 5, in order to improve readability by discussing the docking interface prior to the host interface. B Changed Export Control designation from ITAR to EAR. Made non- 08/2010 technical editorial changes. Updated errata, documenting comments from NDS Baseline Review. C Incorporated changes approved during the NDS Baseline Review. 11/2010 Added definition of -301, -302, -303, and -304 configurations. Added IDs to interface definition requiring verification. Added Section 7.0 describing Host Requirements for NDS Integration. Removed Export Control EAR designation. Document can be released in the public domain. D Updated based on latest Project Technical Requirements Specification 03/2011 and design for Critical Design Review. Refer to Appendix J (Rev. D) for complete list of changes. E Updated based on the closure of open TBDs/TBRs. Updated based on 08/2011 the Critical Design Review RIDs and comments closure. Refer to Appendix K (Rev. E) for changes not covered by RIDs. F Updated based on the closure of open action items (AI). Updated on 12/2011 the closure of open TBDs/TBRs. Updated based on design maturity. Refer to Appendix L (Rev. F) for details. G Updated based on the closure of open action items (AI), the closure of 08/2012 open TBDs/TBRs, the -305 configuration, and the 28 VDC design. Refer to Appendix J for details. H Rev H per SSCN 013982 12-06-13 Revision H is the first release on the ISS Program ERU: /s/Beth Mason 12-6-13 ii JSC 65795 16 November 2013 Revision H PREFACE The contents of this document define the integrated performance and interface design for NASA Docking System (NDS) Block 1 and the International Docking Adapter. The intent of this IDD is to provide the interface design for using, installing, and interfacing to the NDS Block 1 that will enable successful docking to the IDA.
