PREFACE

space station interior and exterior operational location coding system The contents of SSP 30575, Space Station Interior and Exterior Operational Location Coding System, are intended to be consistent with the tasks and products to be prepared by the International Space Station (ISS) participants as defined in SSP 41000, System Specification for the International Space Station. This document establishes the operational location coding system architecture, nomenclature and requirements for the Space Station Program (including International Partners (IPs)). The location coding system will be for the interior (pressurized) and exterior (unpressurized) regions of the Space Station. This location coding system is designed to guide the crew and operations personnel to an area at the Orbital Replaceable Unit (ORU) level of distinction and possibly to a specific ORU, piece part, or utility interface. The ISS utility coding specification establishes the requirements for hazard classification and coding of utility lines.

The contents of this document equally apply to all IPs. This document is under the control of the Space Station Control Board (SSCB). Any changes or revisions will be jointly agreed to and signed by the SSCB.

Revision F introduction purpose This document establishes the operational location coding system architectures, nomenclature and requirements for the International Space Station Program (including International Partners (IPs)). This location coding system is designed to guide the crew and operations personnel to a) an area at the Orbital Replaceable Unit (ORU) level of distinction and possibly to a specific ORU, piece part, or utility interface and b) internal stowage locations in racks.

scope The location coding systems will be for the interior (pressurized) and exterior (unpressurized) regions of the International Space Station (ISS). The operational location coding systems are separate and distinct from the engineering coordinate system. The Russian element location is also specified in SSP 50094, NASA/RSA Joint Specifications Standards Document for the ISS Russian Segment, manner. Labeling requirements for applying location coding markings to the ISS vehicle are contained in SSP 50005, International Space Station Flight Crew Integration Standard (NASA‑STD‑3000/T), Section 9.5.3.1.7.

precedence The requirements in this document are applicable as referenced by the ISS System and Segment Specifications, Prime Item Development Specifications, and component specifications. In case of conflict between this document and any of the ISS specifications, the requirements of the referencing specification will take precedence.

change authority This specification is the responsibility of the International Space Station Program Mission Integration and Operations Office. This document is subject to Space Station Control Board (SSCB) change control.

reference documents The following documents contain supplemental information to guide the user in the application of this document. These reference documents may or may not be specifically cited within the text of this document.

3-8 interior location coding system general description This section describes a common interior alphanumeric location coding system for NASA’s Laboratory Module, Nodes, Airlock, Cupola, European Space Agency (ESA) Columbus Laboratory (COL), ESA Automated Transfer Vehicle (ATV), JAXA H-II Transfer Vehicle (HTV), Japanese Experiment Module - Pressurized Module (JEM-PM), Japanese Experiment Module Experiment Logistics Module Pressurized Section (JEM ELM-PS) and Pressurized Mating Adapter (PMA) and Permanent Multi-purpose Module (PMM). Interior location codes for the Russian segments follow a similar pattern that uses numbered panels rather than rack positions.

General Requirements The orientation of the individual Space Station elements is shown in Figure 3.1-1, Element Orientation. The following reference directions, with respect to the +X, +Y, +Z Local Vertical Local Horizontal Space Station velocity vector, shall be used:

The following three letter identifiers shall be used for the pressurized elements of the Space Station:

Alphanumeric codes have been devised to be as similar as possible for all elements. Where items cross location boundaries, the lowest location code value is used.

Note: The “x” indicates a number placeholder.

figure 3.1-1 element orientation overview The Space Station interior location coding scheme uses a 6 to 9 alphanumeric character system to identify internal Station locations such as elements, truss sections, racks, standoffs, and stowage trays. Figure 3.1.1-1, Examples of Interior Location Coding, depicts an example of the internal location coding system. More detailed descriptions and examples of the location coding system are found in the applicable sections of this document.
