I created an Open-Source Space Simulation toolbox, Open-SESSAME ( which is used for research & education of spacecraft dynamics and controls. It also utilizes a lot of other open-source tools and libraries (such as Doxygen, math library, etc.)

There is a paper in the upcoming Space Mission Challenges in Information Technology conference ( that discusses it and other open-source simulation software.
