Overview
Project Title	CAST Flight Software as a CCSDS Onboard Reference Architecture
Approval	Approved
Document Number
Charter	4.02 Application Support Services Working Group
Document Type	Orange
Description of Document	This experimental report provides an overview of the integration and use of CCSDS standards to enhance interoperability, system commonality of CAST's flight software architecture. It shall cover the following topics: 1. Overview of CCSDS integration into CAST flight software architecture and tool chains. 2. Use of CCSDS standards in the architecture, development tools, and ground systems. 3. Benefits of applied standards to the development, maintenance and operations of spacecraft systems.
Applicable Patents	There are no patent issues for this technology that are known by the CCSDS community
Patent Comments
Survey of Similar Standards Documents or Projects Undertaken in Other Bodies and elsewhere in CCSDS	In parallel there is work planned on Orange books covering the ESA SAVIOR and NASA cFS architectures.
