Details

The Libre Space Foundation (LSF) is a non-profit organization based in Greece, founded in 2014 by the creators of the SatNOGS project. It aims to democratize access to space through the development of open-source hardware and software for satellite missions, ground station networks, and other space technologies. One of LSF's most significant achievements is its contribution to UPSat, the first-ever satellite built entirely with open-source hardware and software. Developed in collaboration with the University of Patras, UP-Sat was launched in 2017 as part of the international QB50 mission. The satellite was designed from scratch with minimal reliance on commercial off-the-shelf components, adhering to open-source principles un-der CERN-OHLv2 and GNU-GPLv3 licenses. LSF has also made strides in other areas of space technology innovation. It developed SatNOGS, the largest open-source satellite ground station network globally, consisting of over 400 stations across more than 50 countries. This network enables affordable satellite tracking and communication for individuals and organizations worldwide. The foundation’s efforts extend beyond technology to education and community building. By collaborating with universities, research institutions, and international organizations such as the European Space Agency (ESA), LSF promotes knowledge sharing and innovation. Educational initiatives like Cronos—a hybrid-fueled sounding rocket project—illustrate its dedication to inspiring future generations of engineers and scientists while fostering inclusivity in space exploration. Through its pioneering projects like UPSat and SatNOGS, LSF has demonstrated how open-source principles can revolutionize access to space. Its work not only advances technological capabilities but also fosters international collaboration and democratization of space exploration. By prioritizing openness and accessibility, LSF continues to pave the way for a more inclusive future in space science and engineering.
