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://fprime.jpl.nasa.gov for more information.
- 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.

The following system requirements apply to your workstation for developing F´ applications. To see the list of supported platforms on which F´ applications can run on, see Supported Platforms.
-
Linux, Windows with WSL, or macOS operating system
-
Clang or GNU C and C++ compilers (e.g. gcc and g++)

-
git --version -
python --versionandpython -m venv -h. Your system might use an alternate likepython3orpython3.13. For pip:pip --version. On your system it might bepip3orpipx. -
g++ --versionand then create, build, and run a test program. For example, create a file namedhello.cppwith contents:#include <iostream> int main(void){ std::cout << "Hello, World!" << std::endl; }
then build and run it, for example like:
% g++ -o hi hello.cpp % ./hi Hello, World!
To get started with F´, install the F´ bootstrapping tool with:
pip install fprime-bootstrap
Then, create a new project with:
fprime-bootstrap project
See the HelloWorld Tutorial to guide you through all the steps of developing an F´ project.
New users are encouraged to read through the User Manual and explore the other tutorials.
