Overview
Project Title	Space Packet (SPP) and Encapsulation Packet (EPP) Protocols - Summary of Concept and Rationale
Approval	Approved
Document Number	130.3
Charter	5.04 Space Link Protocols Working Group
Document Type	Green
Description of Document	This Green Book contains both the concepts and rationale of the “SPP/EPP”. The rationale for one common book is to: a) To provide an overview on the concepts of both the Space Packet and Encapsulation Packet Protocols from a user’s perspective; b) To provide information on how these packet protocols could be used by end users to efficiently develop their mission systems (including onboard instruments and ground support systems); c) To provide use cases on how these packet protocols could be deployed by Mission Operations into space data systems to achieve interoperability amongst multiple agencies (including both onboard and ground infrastructures).
