Open Cosmos (Barcelona, Spain) has established a new low-Earth-orbit (LEO) satellite constellation, ConnectedCosmos, for secure communications across Europe and the United Kingdom (UK). The satellite constellation, operating within Ka-band spectrum, will also connect the Earth observation (EO) capabilities deployed in the firm’s Open Constellation to provide real-time data wherever needed.

The new constellation provides broadband point-to-point services with direct-to-device Internet of Things (IoT) connectivity. The constellation employs optical inter-satellite links (ISLs) for continuous communications with minimal hardware infrastructure, such as subsea cables. The ISLs also help minimize the threats of interference from cyberattacks and jamming (see image above)

Open Cosmos, with a goal of providing secure communications from space, employs manufacturing facilities in the UK, Spain, Portugal, and Greece, and plans expansion to additional locations throughout Europe. The company collaborates with sovereign partners to best serve each area. 

The firm’s CEO and founder, Rafel Jordà Siquier, said, “ConnectedCosmos represents a leap forward for Europe in building a resilient, secure, and autonomous connectivity capability — giving nations and partners a reliable alternative for true sovereignty in orbit.” 

He added, “In a world where infrastructure can be disrupted, jammed, or compromised, our constellation ensures that critical data remains secure, trusted, and immediately usable. With ConnectedCosmos, we are delivering to the world an alternative that matches technological excellence with strategic autonomy.”
