Barcelona-based satellite operator Sateliot has announced the launch of a Series C financing round for €100 million, a strategic move designed to accelerate the deployment of its ambitious 5G satellite network. The capital injection is earmarked for the rollout of a constellation consisting of 16 satellites, marking a significant escalation in the company’s effort to provide global 5G IoT connectivity from space.
This funding push comes at a critical juncture for the European space sector as the industry pivots toward “Fresh Space” commercialization. By integrating satellite technology with terrestrial 5G standards, Sateliot aims to eliminate connectivity gaps for Internet of Things (IoT) devices, ensuring that critical data can be transmitted from the most remote corners of the globe without requiring specialized, proprietary hardware.
The move signals more than just corporate growth; it is a bid for European technological sovereignty. By developing a network that adheres to common global standards, Sateliot is positioning Spain and Catalonia as central hubs for a new era of telecommunications infrastructure that blends orbital assets with mobile network operator requirements.
Building the Infrastructure: The Barcelona Development Center
The financing round follows a major infrastructure milestone. On November 10, 2025, Sateliot inaugurated the first European 5G Satellite Development Center in Barcelona. Located at the company’s new headquarters, this facility serves as the primary site for the design, development, and verification of 5G satellites. Crucially, these satellites are built under 3GPP standards, ensuring they are compatible with all mobile operators globally.
The center represents the beginning of Sateliot’s industrial phase. The facility is equipped with a 100m² clean room, a dedicated laboratory, and a mission control room, providing the technical environment necessary to move from prototypes to mass deployment (iotm2mcouncil.org). This local investment has already had a tangible impact on the regional labor market, driving the creation of more than 50 highly skilled jobs and allowing Sateliot to double its workforce over the past year (sateliot.space).
The inauguration of the center saw high-level institutional support, attended by figures including Salvador Illa, President of the Government of Catalonia, and Juan Carlos Cortés, Director of the Spanish Space Agency (AEE). This level of backing underscores the strategic importance of the project for European security, defense, and communications autonomy.
The Tritón Satellite: Technical Capabilities and Dual-Use
At the heart of the new constellation is a new generation of satellites named “Tritó,” a tribute to the Montseny newt, an amphibian species endemic to Catalonia. These satellites represent a qualitative leap in performance over previous iterations. Each Tritó satellite measures nearly four meters in length and weighs 150kg, featuring increased operational power in their payloads (iotm2mcouncil.org).
While the primary focus remains on IoT connectivity, the Tritó satellites are designed for versatility. They will support not only IoT devices but also standard mobile phones, enabling data, voice, and video services from space. The satellites feature dual-use capability, meaning they can be deployed for both commercial applications and critical government functions, including civil protection, security, and national defense (iotm2mcouncil.org).
This technical flexibility is bolstered by a historic milestone achieved in October 2025, when Sateliot successfully demonstrated the world’s first direct 5G-IoT connection from space using standard IoT devices. This proof-of-concept validates the company’s approach to using 3GPP standards, proving that space-based 5G can operate seamlessly with existing hardware.
Strategic Impact on the New Space Industry
The transition to an industrial phase, supported by the €100 million Series C round, places Sateliot in a competitive position within the “New Space” sector. By focusing on the intersection of 5G and satellite technology, the company is addressing a critical gap in the global telecommunications matrix: the “dead zones” where terrestrial towers cannot reach.
The implications for the IoT market are substantial. Industries such as logistics, maritime shipping, agriculture, and environmental monitoring rely on constant data streams. The ability to maintain a 5G connection via satellite without needing specialized satellite modems reduces the barrier to entry for companies looking to digitize their remote operations.
the project enhances Europe’s technological autonomy. By developing these capabilities within Barcelona, Sateliot reduces reliance on non-European satellite constellations for critical IoT infrastructure, aligning with broader European Union goals regarding technological sovereignty and secure communications.
Key Takeaways: Sateliot’s Expansion
- Funding Goal: Seeking €100 million in Series C financing to deploy a 16-satellite 5G constellation (eu-startups.com).
- Infrastructure: Inaugurated a European 5G Satellite Development Center in Barcelona in November 2025 (sateliot.space).
- Technical Specs: The “Tritó” satellites weigh 150kg and measure nearly four meters, supporting voice, data, and video (iotm2mcouncil.org).
- Standards: Fully compliant with 3GPP standards, ensuring compatibility with all global mobile operators.
- Economic Impact: Created over 50 high-skilled jobs and doubled the company’s workforce within one year (sateliot.space).
As Sateliot moves forward with its financing round, the industry will be watching for the selection of a lead investor to anchor the Series C. The successful deployment of the 16-satellite constellation will serve as the next major benchmark for the company’s ability to scale 5G IoT connectivity on a global level.
