Core Flight System (cFS) is a NASA multi-center open source flight software framework with a layered architecture and international standards-based interfaces. It provides tools, runtime environments, and reusable artifacts for user applications. The framework has a worldwide community from government, industry, and academia. Learn about the historical context and evolution of cFS from its inception to community development.

What is the Core Flight System (cFS) ? A NASA multi-center configuration controlled open source flight software framework Layered architecture with international standards-based interfaces cFE Application Programmer Interface Provides development tools and runtime environment for user applications Core Flight Executive Implementation Platform Application Programmer Interface Reusable NASA Class A/B lifecycle artifacts: requirements, design, code, tests, and documents Platform Implementation The framework is ported to a platform and augmented with applications to create Core Flight System (cFS) distributions User Applications Core Flight Executive Platform Implementation A worldwide community from government, industry, and academia 3
cFS Historical Context < 2007: Birth of core Flight Executive (cFE) - NASA Goddard Space Flight Center performed an assessment of FSW reuse to date, heritage analysis, architectural trades - Project independent funding kick started the effort - Operating System Abstraction Layer (OSAL) released as open source 2007: cFE goes to the Moon - Lunar Reconnaissance Orbiter (LRO) first to use OSAL & cFE 2008 2014: Birth of core Flight System (cFS) - cFE released as open source - Goddard developed 12 cFS applications - Leveraged project funding - JSC certified Class A pedigree of cFE targeted to the ARINC-653 4
cFS Historical Context (cont.) 2014: Birth of a Community - cFS NASA Workshop (12/14 at GRC) established a NASA-wide repository managed by a NASA multi-center Configuration Control Board (CCB) 2015: Community Youth - 12 Goddard applications released as open source - CCB successfully released cFE 6.4.2 - cFE functional Application Programmer Interface (API) is unchanged since LRO - Held first cFS Workshop at Johns Hopkins Applied Physics Lab 2016-2018: Community Adolescence - CCB successfully released cFE 6.5.* and cFE 6.6 - NASA Johnson contributes tools and apps - Held cFS Workshop each year 5
Helpful Architecture View Software application architecture is the process of defining a structured solution that meets all of the technical and operational requirements, while optimizing common quality attributes such as performance, security, and manageability. Systems should be designed with consideration for the user, the system (the IT infrastructure), and the business goals. Ref: Microsoft Application Architecture Guide, 2nd Edition https://msdn.microsoft.com/en-us/library/ee658098.aspx 6
cFS Evolution: User Perspective Users have expanded from a Goddard branch to a global community - Universities, commercial businesses, government agencies, hobbyist Different users have different QA priorities - E.g. universities want ease of deployment DoD has only expressed a cursory interest - Security was a low priority QA for Goddard High demand for information that was people centric at Goddard - Systems engineering documentation, help desk, and training Frustration with quasi-open source project - Government rules and regulations prevent the government from running a conventional open source community 7
cFS Evolution : System Perspective What has scaled well with increased user base - Scheduler as an app - API stability What has not scaled well - Artifacts developed for Goddard-specific environments and have not been transformed to a general purpose solution Table generation tools Build test scripts - Lack of documentation Ongoing conversations - Binary vs Text Tables - File systems: When, where, and how to use them - Single command & telemetry definition with toolchain generated artifacts 8
cFS Open Source: Business Perspective The NASA user base has expanded to an international community Lunar Orbiting Platform Gateway (LOP-G) has the cFS in it s requirements in part because of the interoperability QA Current business model unsustainable & inefficient Help desk is borrowed time Tax local projects because we can Missed opportunities in gaining experience from product cycles and user contributions The product model and community infrastructure is immature Online component and distribution catalogs cFS mailing list used as primary Q&A forum Challenges with government run open source programs Funding Software release processes and licensing 9
