El 6GStarLab It is already orbiting the Earth and has become one of Europe's most unique space projects. It is a Catalan satellite in low Earth orbit which will act as a test laboratory for the next generation of mobile communications, 6G, and for so-called non-terrestrial networks.
This nanosatellite, developed with entirely Catalan technology, has been launched from SpaceX's Vandenberg base (California, United States) to about 500 kilometers highFrom the beginning of 2026 it will be used as open test bench for researchers, companies and technology centers that want to validate advanced connectivity solutions directly in space.
A pioneering 6G laboratory in low Earth orbit
The 6GStarLab presents itself as the first European open 6G research laboratory in low Earth orbitwith a very clear mission: to bring the research done in laboratories on land closer to a real environment in spaceFrom the satellite, experiments can be deployed and executed remotely, testing new architectures and communication protocols.
According to the research center i2CAT, which is leading the initiative, this satellite becomes a key piece for the European digital ecosystem by offering a collaborative testbed for 6G and non-terrestrial (NTN) networks. The goal is to facilitate the validation of technologies that integrate the scientific community and industry. terrestrial and satellite networks in the same system.
The mission will allow experimentation with high-capacity, low-latency services that should eventually reach rural areas and isolated areas where coverage is currently poor or nonexistent. The idea is that the future 6G, combined with non-terrestrial networks, will help close the digital divide and enable stable access to essential services.
This approach fits with the vision of the European Space Agency (ESA)which is promoting the creation of several open laboratories in orbit. The Catalan project has taken the lead, positioning itself as one of the first platforms of this type in Europe and aligning itself with the EU's technological sovereignty strategy vis-Ã -vis other powers.
100% Catalan design and express construction
The satellite was built by the company Open Cosmos at its Barcelona facilities, following a public contract awarded by i2CAT valued at around 1,65-2 billion eurosAccording to various official estimates made public, this amount covers the design, manufacture, integration, launch, and commissioning in orbit.
Of compact size, the 6GStarLab falls into the category of nanosatelliteIt has approximate dimensions of 20 cm long, 10 cm wide, and 30 cm high, with a weight slightly over 11 kg. Other descriptions mention a device weighing between 10 and 15 kg and about half a meter long, but in all cases it is a compact satellite designed for agile and cost-effective missions.
One of the project's highlights is the execution time. From the signing of the contract to the delivery of the satellite, only a few days passed. less than nine monthsThis is an unusually short timeframe for the space sector, where developments typically take several years. Both i2CAT and Open Cosmos point to this pace as a milestone within the industrywhich demonstrates that it is possible to execute complex space missions with less budget and greater speed.
The platform integrates high-tech payloads Designed by i2CAT and the Catalan company Microwave Sensors and Electronics (MWSE), specializing in advanced electronics. The radio frequency antenna array was developed by NanoSat Lab of the Polytechnic University of Catalonia (UPC), specializing in small satellites. In addition, the international company Transcelestial, based in Singapore, is participating, contributing a optical communication laser terminal and its associated ground station.
How was the launch with the Falcon 9?
The 6GStarLab was put into orbit using a rocket Falcon 9 Block 5 from SpaceX, the reusable version that has been operational since 2018 and has already accumulated more than 550 missions carried outThe launch took place from Vandenberg Air Force Base in California, in a mission shared with more than a hundred satellites.
The Falcon 9 is structured in two stages that function in a coordinated manner. The first, known as boostIt is responsible for providing the initial thrust that allows the rocket to break through the atmosphere. Approximately two and a half minutes after liftoff, this stage separates from the rest and returns autonomously to Earth to be reused in future launches, a common practice at SpaceX.
The second stage, lighter and adapted to the vacuum of space, is the one that transports the satellites to the planned orbit and gives them the final push. In this mission, a set of devices was released, including the Catalan nanosatellite, which were deployed progressively once the appropriate altitude was reached.
When the 6GStarLab was released, the satellite itself activated automatically, determining its position in orbit and stabilized to begin initial operations. The entire process, from rocket launch to satellite stabilization, was completed around one hour long, according to those in charge of the project.
At this time, the preliminary technical tests to verify that all systems are functioning correctly. If the schedule is met, the satellite will become fully operational for research purposes early next year, serving as a platform for multiple experimental campaigns during a estimated useful life of between three and five years, after which it will disintegrate re-enter the atmosphere.
Non-terrestrial networks and the future of 6G
The integration of terrestrial and non-terrestrial networks is destined to be one of the major changes in the advanced 5G and, above all, the future 6GThis approach aims to offer more stable and continuous connectivity, even when a person is moving through poorly covered areas or in situations where terrestrial infrastructure may fail.
The project's promoters emphasize that this laboratory will allow them to test solutions designed for Improve connectivity in rural and isolated environmentswhere even today there are still basic problems such as being able to make a call or connect to the internet reliably. The possibility of using low-Earth orbit satellites to complement the terrestrial network is seen as the most realistic way to achieve a full coverage of the territory.
In addition to general connectivity, the mission will serve to test critical applications such as the telemedicine and distance educationwhich require stable, low-latency data links. Work is also planned on use cases related to the autonomous mobilitywhere constant communication between vehicles and control centers will be essential.
Another of 6GStarLab's strengths is its contribution to the development of secure communicationsThe experiments in orbit are expected to help define new generations of protection systems against cyberattacks. solar activitydesigned to protect critical infrastructure, financial services, public administrations, and personal communications.
Applications in emergencies and natural disasters
One aspect that is given special importance is the satellite's ability to contribute to the prevention and management of natural disastersFrom i2CAT and the scientific ecosystem involved, the focus is on tests aimed at the detection and monitoring of forest fires and other extreme phenomena, where having resilient communications can make all the difference.
Combining data from space with information from the ground will allow testing of systems for early warning and coordination more sophisticated. In both fires and floods, the ability to maintain data flow even if terrestrial infrastructure is damaged is a critical element for civil protection.
Beyond emergencies, these types of networks could be used to constantly monitor the state of the territoryproviding useful information for natural resource management, precision agriculture, and monitoring the impact of climate change. Although the 6GStarLab is not dedicated to Earth observation, its role as a laboratory will help to test protocols and capabilities which can then be integrated into other satellites and missions.
Statements from ESA and government officials indicate that this is a significant step for Spain, and in particular, Catalunya, consolidate a leading position in the field of Space innovation applied to telecommunicationsThe project does not yet offer a direct service to citizens, but it is clearly conceived as an investment in knowledge and capabilities for the coming years.
In the words of industry experts, the 6GStarLab is designed to pave the way for the market and the local industrycreating an environment where companies can test solutions before making the leap to commercial deployments. In a context where 5G development has already shown implementation difficulties, it is believed that these types of platforms will allow for better anticipation of which 6G technologies may have a real impact.
Ground optical station in Móra la Nova
The satellite's mission is not limited to space. The project includes the creation of a land segment in Móra la NovaIn the Terres de l'Ebre region (Tarragona), this facility will become a key point for controlling experiments and managing data. It will be located in the Molló industrial park, near the COEbre LAB social innovation laboratory.
This segment will oversee the operations of the 6GStarLab and coordinate the testing campaigns, both in radio frequency as in optical communicationsThe infrastructure is being promoted with co-financing from Nuclear Transition Fund and the Secretary of Digital Policies of the Generalitat, with the intention of strengthening the technological fabric in a region that is seeking new economic opportunities.
One of the most unique elements will be the installation of a pioneering terrestrial optical station in Cataloniacapable of establishing bidirectional laser links between Earth and the satellite. This type of optical communication allows the transmission of large volumes of data at high speed and with less interference than traditional solutions based solely on radio frequency.
The laser technology tested at this station is considered a a preliminary step towards quantum communicationswhich in the future could be used to exchange information extremely securely using principles of quantum physics. Although this is still under development, the 6GStarLab will serve to test some of the necessary technological building blocks.
The choice of Móra la Nova is also part of a broader strategy by the Generalitat to decentralize key digital infrastructures and link them to innovation projects such as the proposed future artificial intelligence gigafactories in the area. In this way, the satellite's impact extends beyond the strictly scientific and technological sphere.
Funding, technological sovereignty and European strategy
The 6GStarLab project is integrated into the state program Unique R&D 6G, aimed at the universalization of digital infrastructures and financed with NextGenerationEU fundsWithin this framework, i2CAT obtained around 10 millones de euros for various research infrastructures, of which 1,65 million have been allocated directly to the satellite.
Additionally, the Generalitat has linked this mission to its Catalunya Espai Strategy 2030which envisions an approximate investment of 150 million euros over five years and the launch of up to eight satellite missions focused on Earth observation and communications. The 6GStarLab is positioned as one of the spearheads of this Catalan space agenda.
The policymakers involved emphasize that initiatives like this seek to strengthen the European technological sovereignty In the face of advances by the United States and China in the space and telecommunications sectors, having its own 6G laboratory in low Earth orbit is considered a further step towards not depending exclusively on external infrastructure.
The central government has emphasized that the speed of change in the digital world This suggests that the impact of projects like 6GStarLab could be felt relatively soon in terms of knowledge generated and transferred to the productive sector. Although 6G technology will still take some time to reach the end user, the tests carried out in these types of trial camps will determine which solutions ultimately succeed.
Experts from the ESA and academia see this satellite as a tool for Spain and Catalonia to position themselves at the forefront of space research applied to telecommunicationswithout losing sight of the fact that the real challenge will be to transform these advances into real benefits for society and for the European private sector.
With the 6GStarLab already in low Earth orbit and the first technical tests underway, the project is establishing itself as an example of collaboration between administrations, research centers and companies around a common goal: to develop from Europe the next generation of communications networks by combining satellites and terrestrial systems, improve connectivity in the areas that need it most and prepare the ground for new applications in emergencies, mobility, digital services and communications security.
