4S Symposium 2026

The 4S Symposium 2026 (Small Satellites Systems and Services) will take place from May 4–8, 2026, in Sardinia, Italy. Held every two years, this event has become a key international forum for the small satellite community.

The symposium brings together industry leaders, space agencies, and academic experts to share insights, showcase innovations, and foster collaboration. Its program includes technical sessions, keynote presentations, exhibitions, and networking opportunities. The 2026 edition, under the theme “Swarming the Skies, Soaring Beyond: from VLEO to Deep Space,” will explore emerging trends such as new mission architectures, advanced technologies, and innovative applications across the space sector.

In this context, GMV will participate as a Silver Sponsor, highlighting its strong commitment to advancing cutting-edge space solutions and reinforcing its position as a key player within the global small satellite ecosystem.

Within the technical program of the symposium, GMV professionals will have a strong presence through several presentations and key roles across different session. Our colleague Rafael Contreras, Space Systems Engineer and Project Manager at GMV, will present “Celeste First In-Orbit-Demonstration Satellite and Positioning, Navigation and Timing Payload Design, Development, Manufacturing and Ground Validation”.

In addition, Mariella Graciano, GMV’s Space Systems EST Strategy and Business Development of Science, Exploration and Transportation Director, will deliver the presentation “Architecting Resilient and Sustainable Orbital Ecosystems through Industrial Small Satellite’s In-Orbit Demonstrators”. Mariella Graciano will also serve as chair of the session “New Technologies 1.”

Colleagues from Alén Space will also actively participate in the event: Alberto Mañero will present: “Celeste IOD: Adapting COTS CubeSat Platforms for High-Performance LEO-PNT Missions”. Additionally, Iván Rodríguez will participate as co-author of the paper presented by ESA titled: “The Spanish Component of the Atlantic Constellation (ESCA): Small Satellites for Rapid Earth Observation Multi-Domain Applications”.
