Engineers.
Radio operators.
Space nerds.
A non-profit foundation registered in Greece since 2015. We build open-source technologies for space — from ground stations to satellites — and we publish everything we make, so anyone, anywhere, can do it too.
Ten years, in the open.

The crew on the ground.
Cleanroom. Repos. Ground stations.
Since April 2025 our work happens at a dedicated Athens headquarters with a cleanroom and TVAC chamber — the rooms where PHASMA was integrated and where the next flight hardware is built. Alongside them run the usual rhythms: GitLab reviews, Matrix threads, Sunday solder sessions, the SatNOGS Network humming in the background.
Pull requests from strangers ship to orbit. Bug reports from amateurs fix production firmware. Students run the ground stations that track the spacecraft we build with them. That ratio — a small staff, a worldwide community — is the foundation.
Partners in the open.
