Open Cosmos has announced ConnectedCosmos, a new low Earth orbit (LEO) satellite constellation designed to deliver sovereign, secure and resilient communications services to governments and businesses worldwide.
The initiative aims to reduce reliance on large transcontinental mega-constellations by integrating the company’s existing Earth Observation capabilities from its Open Constellation with a new sovereign connectivity backbone in LEO. The system is intended to enable real-time data access and secure communications wherever they are needed.
ConnectedCosmos combines point-to-point broadband connectivity with direct-to-device Internet of Things (IoT) services, allowing users to monitor potential threats in real time and act on actionable intelligence. Open Cosmos describes the offering as an “active” resiliency service, built to support rapid and informed decision-making in high-stakes environments.
Amid rising geopolitical tensions and growing concerns over infrastructure vulnerability, the company said the constellation offers nation states, institutions and enterprises a way to build independent and secure communications networks. Using Optical Inter-Satellite Links (ISL), ConnectedCosmos forms a gateway-less space-based mesh network that routes data directly between satellites. This approach is designed to bypass vulnerable subsea cables and terrestrial infrastructure, reducing exposure to jamming, cyberattacks and other forms of interference.
The constellation will operate using high-priority Ka-band spectrum filings from Liechtenstein, which Open Cosmos reactivated earlier in 2026 with the launch of the first satellites in the network. The company said this spectrum access will help users navigate an increasingly congested and competitive orbital environment.
Commenting on the new constellation, Rafel Jordà Siquier, Founder and CEO of Open Cosmos, 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.
“By combining secure space-based communications with real-time Earth Observation intelligence, we are moving beyond connectivity alone and delivering actionable resilience. This combination is what separates us from the crowd – adding the extra layer of context and insight to transform our offering into a unique service.
“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.”
Open Cosmos operates manufacturing facilities across the UK, Spain, Portugal and Greece, with further expansion planned. The company also works closely with sovereign partners in the regions it serves. Throughout 2026, Open Cosmos expects to expand the constellation through additional satellite launches and new partnerships, supporting continued growth across Europe.
