A Flight-Proven, Multi-Platform, Open-Source Flight Software Framework

# F´ (F Prime) is a component-driven framework that enables rapid development and deployment of spaceflight and other embedded software applications. Originally developed at the Jet Propulsion Laboratory, F´ has been successfully deployed on several space applications. It is tailored but not limited to small-scale spaceflight systems such as CubeSats, SmallSats, and instruments.

Please Visit the F´ Website: https://nasa.github.io/fprime for more information.

What does F´ provide

• An architecture that decomposes flight software into discrete components with well-defined interfaces
• A C++ framework that provides core capabilities such as message queues and threads
• Modeling tools for specifying components and connections and automatically generating code
• A growing collection of ready-to-use components
• Testing tools for testing flight software at the unit and integration levels.
