Overview
Project Title	RFID Tag Encoding Specification
Approval	Approved
Document Number	881.1
Charter	4.03 Onboard Wireless Working Group
Document Type	Blue
Description of Document	NASA proposes to work with the FSA, ESA, CSA, and other interested CCSDS members to develop a Blue Book that addresses an RFID tag encoding standard. It is assumed that the tag encoding standard would be consistent with the existing SOIS Magenta Book, “Spacecraft Onboard Interface Services – RFID-Based Inventory Management Systems”. Hence, the proposed tag encoding standard would determine the tag encoding structure for the identification code in the ISO 18000-6C (EPCglobal Class 1 Gen-2) standard. The proposed scope would include determination of the requirements for a tag encoding standard. For example, it is likely that such a standard would incorporate a designator for the organization owning the item. The associated database and tag purpose are additional possible identifiers embedded in a tag encoding structure. A notional example of 96-bit tag encoding structure is shown in Fig. 1. It should be noted that many tags consistent with the CCSDS Magenta Book, “Spacecraft Onboard Interface Services – RFID-Based Inventory Management Systems” now offer 128 identification bits as opposed to the previous 96 identification bits, in addition to user memory.

Patent Comments
Survey of Similar Standards Documents or Projects Undertaken in Other Bodies and elsewhere in CCSDS	This CCSDS standard provides a standards-based transition path to the EPCGlobal Class-1 Gen-2 / ISO 18000-6C RFID tag-encoding standard. Because of the RFID tag-encoding utilized onboard the International Space Station the WWG needed to support the current (onboard ISS) tag-encoding and provide a transition path to a fully-compliant EPC namespace management schema for future utilization. A valid analogy is to think of the current ISS naming schema as "2G" (in telecomm parlance) and implementation of the recommended RFID tag-naming specification as a migration to "3G/4G". Future versions of this standard can (and may) include strong security mechanisms for authentication, authorization, and integrity – so a "5G" type of evolution. Thus this project seeks to adopt the ISO 18000-6c / EPCglobal tag-encoding specification in a managed evolution process to be fully EPC compliant. We are building upon the significant work of EPC and ISO in this regard that is widely utilized in commercial and government sector applications
Resources
Book Editor	NASA
Book Editor Resources	0.15my (Note: 230h considers only the resources for the Agency leading, in this case NASA)
Prototype 1	NASA
Prototype 1 Resources	0.2my Note: The scope of the prototyping MUST include verification of all aspects of the tag-encoding schema. This SHALL be a verification of the software required to implement the tag-encoding schema by two agencies (FSA and NASA). The prototype may include - Writing the encoding scheme to a set of tags; - Reading the tags and verify that the correctness of the data in relation to the encoding scheme; - Interoperability testing (reading & verifying the FSA tags with NASA equipment in relation to the encoding scheme) - Document the testing and Results
Prototype 2	FSA
Prototype 2 Resources	0.2my Note: The scope of the prototyping MUST include verification of all aspects of the tag-encoding schema. This SHALL be a verification of the software required to implement the tag-encoding schema by two agencies (FSA and NASA).

Monitor Only	CNSA
Resource Comments	NASA is much more ahead in its implementation of RFID systems when compared to FSA and ESA, which may require greater FSA resources for the prototyping phase.
