SWISSto12

SWISSto12 is a leading manufacturer of advanced satellite Radio Frequency (RF) products, payloads, and systems based in Renens, Switzerland. The company's flagship product is the HummingSat, a small yet powerful geostationary telecommunications satellite developed in collaboration with the European Space Agency (ESA). HummingSat is approximately one-fifth to one-third the size and weight of conventional satellites, making it more cost-effective and flexible for operators. SWISSto12's technology utilizes patented 3D-printing techniques to create lightweight, compact, and high-performing RF components and systems. This approach allows for the production of satellites that are about the size of a washing machine, significantly smaller than traditional satellites. The company's product portfolio includes RF subsystems, satellite payloads, and complete satellite systems. As of March 2024, SWISSto12 had four connectivity satellites under construction: one for Intelsat and three for Viasat, all scheduled for launch to geostationary orbit in 2026. The company has generated over EUR 200 million in customer orders across its satellite and RF business. To meet growing demand, SWISSto12 expanded its production facilities in Switzerland, adding 1,200 square meters of space to its existing 4,500 square meter site in March 2024, bringing the total area to 5,700 square meters.

Key customers and partnerships

SWISSto12 has secured contracts with major satellite operators including Intelsat and Inmarsat (acquired by Viasat in 2023). The company supplies satellites and RF systems to other prominent companies in the aerospace and defense industry, such as Thales, Lockheed Martin, and Northrop Grumman. In May 2023, SWISSto12 partnered with Inmarsat to develop three I-8 satellites based on the HummingSat platform, enhancing network resilience and ensuring the continuity of Inmarsat's global L-band safety services. These satellites are scheduled for launch in 2026. Additionally, SWISSto12 has collaborated with CAES (Cobham Advanced Electronic Solutions) to develop additively manufactured phased array antennas for Lockheed Martin Space. The company has also formed strategic partnerships with SatixFy to boost the development and commercialization of end-to-end MEO and GEO telecom satellite payloads, and with RUAG Space to supply future satellite missions with antenna solutions.
