SWISSto12 Accelerates its Global Satellite Momentum
As 2025 draws to a close, SWISSto12 has reflected on a year of major advances in its GEO smallsat manufacturing, phased-array RF technologies, and global expansion, claiming it has positioned the Swiss company as a central player in Europe’s push for satellite sovereignty.
The company has reported significant progress on the first four of its HummingSat units, ultra-compact GEO telecommunications satellites ordered by SES (IS-45 program) and Viasat (I-8 program). Both programs are moving toward Critical Design Review in early 2026, with flight hardware now entering assembly.
HummingSat’s momentum has been further reinforced by its selection for Astrum Mobile’s NEASTAR-1, the APAC region’s first GEO satellite-to-device platform. The system, which has been designed for media delivery, IoT connectivity, mass notification and emergency alerting, cleared Preliminary Design Review in September.
SWISSto12 has also advanced its roadmap for electronically steered antennas (ESAs) tailored for HummingSat missions and for LEO/MEO/GEO third-party platforms, and has successfully demonstrated live phased-array operations.
Also on show this year was HummingLink-SOTP, a portable multi-band GEO user terminal leveraging its proprietary 3D-printed RF components across Ka-, Ku-, and X-band, aligned with growing demand for flexible, sovereign ground networks.
Among its list of acheievements, SWISSto12 (also) opened a new Madrid facility focused on satellite systems and user terminal development, expanding its manufacturing footprint and proximity to European industry partners. In the U.S., the company upgraded its Georgia Command and Control Center, adding digital twin environments and next-generation electric orbit-raising capabilities ahead of HummingSat’s first launches in 2027.
The company’s growth aligns with a wider push across Europe to secure independent GEO infrastructure, resilient communications, and sovereign RF technologies, all areas where SWISSto12’s compact, rapidly manufactured GEO platforms are increasingly viewed as strategically important.
