Value through innovation, impact and efficiency
The space sector is a pillar of technological progress, demanding precision, innovation, and full reliability. At Sener, we have been driving space engineering, aerospace manufacturing, and space exploration since 1967. Our capabilities extend across the full spectrum of products and technology for satellites and launchers in institutional, telecommunications, and scientific programs, with the ability for repeated series production. We collaborate with the most prominent agencies, including ESA, NASA, and JAXA, to bring forward-thinking solutions to some of the most complex missions ever launched.
How we support you in the space industry
Advanced engineering and in-house technologies for satellites, launchers, communications, Earth observation and in-orbit services.
We bring over five decades of expertise in designing, manufacturing, and qualifying electromechanical systems for space. Our deployment and pointing mechanisms, antennas, and robotics consistently meet the most rigorous standards. With a 100% in-orbit success rate, our equipment has never failed — and we work every day to keep it that way.
We are driven by a clear mission: to turn technological complexity into performance and long-term reliability. Our industrial commitment is evident in every subsystem we deliver — from launchers and orbiters to communication satellites and scientific platforms. We are trusted to deliver high-performance systems because we always strive for the highest quality.
We have delivered over 10,000 onboard components for more than 1,400 satellites. Our electromechanical systems, RF systems, GNC technologies, and electronic equipments have become mission-critical in programs such as Space Rider, Euclid, and SpainSat NG. These milestones reflect the trust placed in us by space agencies and industry leaders alike.
We cover the entire lifecycle of a project — from concept and detailed design to production, integration, qualification, and long-term support. We deliver complete solutions that combine mechanical, electrical, and software systems, all validated in our own facilities.
We lead Proba-3, where we demonstrate high-precision formation flying to study the solar corona. In JUICE, our pointing and deployment mechanisms support the exploration of Jupiter’s icy moons. For Euclid, we supply key communications equipment for one of ESA’s major scientific missions.
Sener applies over 50 years of multidisciplinary expertise to the space sector, delivering reliable solutions in mechanisms, navigation, communications and power electronics. Our engineering excellence ensures consistent, high-performance support across every stage of space mission development and operation.
