Vilnius, Lithuania – July 4, 2025 Astrolight, a Lithuanian space-technology start-up based at Vilnius Tech University, has secured €2.8 million ($3.3 million) in funding to develop advanced laser communication systems intended to revolutionize satellite-to-Earth data transmission. Against the backdrop of increasing satellite launches and growing geopolitical tensions in Eastern Europe, Astrolight’s technology promises faster, more secure, and higher-capacity optical data links that could transform both civilian and military communications.
A New Era for Satellite Communication: The Rise of Optical Data Highways
Astrolight’s cutting-edge system utilizes laser technology as an “optical data highway,” offering a faster and more secure alternative to traditional radio frequency (RF)-based satellite communications. With an estimated 70,000 satellites expected to be launched globally over the next five years, demand for efficient and reliable data links has never been higher.
“We envision shifting from conventional RF communication to high-bandwidth, hack-resistant laser systems,” explained Laurynas Maciulis, CEO and co-founder of Astrolight. “Laser beams enable targeted, secure, and high-speed data transmissions that are difficult to intercept or jam.”
The system leverages laser light in narrow beams to transmit data between satellites and ground stations, essentially creating invisible “internet cables” across space. This innovation holds significant promise for the commercial satellite sector, which is poised for rapid growth due to increasing demand for broadband internet, Earth observation, and data services.
Defence Applications Amid Heightened Regional Security Concerns
Beyond commercial usage, Astrolight’s technology is gaining traction within defence circles. The company is a participant in the NATO Defence Innovation Accelerator for the North Atlantic (DIANA) programme, established in 2023 to accelerate the integration of civilian technologies into military applications.
Lithuania’s Navy approached Astrolight three years ago seeking communication equipment capable of operating covertly under radio silence conditions. The company adapted its space-oriented laser technology to terrestrial applications, enabling secure, undetectable communication between military vessels.
“Radio transmissions can be easily tracked and targeted, especially in conflict zones like Ukraine. Our laser communications offer ‘low detectability’, as the narrow beam is incredibly difficult to detect or intercept,” Maciulis said.
The utility of such technology is underscored by ongoing regional hostilities and Lithuania’s proximity to Russia, whose aggressive posture has prompted NATO members to reassess and strengthen their defence capabilities.
Lithuania’s Strategic Investment in Defence and Space Innovation
Although Lithuania’s overall defence budget valued at approximately £2.5 billion annually is modest compared to larger nations such as the UK (£54 billion), the country allocates a notably higher share of its GDP to defence: 3% currently, trending towards 5.5%. The UK, by comparison, commits 2.5% of its GDP.
Invest Lithuania’s head of manufacturing and defence sectors, Šarūnas Genys, affirmed the strategic role of space technology in national security. “Space capabilities have become integral to Lithuania’s defence and resilience strategies,” he stated. “Technologies developed for space missions are increasingly dual-use, benefiting both civilian sectors and military operations.”
EU funding has bolstered Lithuania’s burgeoning space industry, with 30% of local projects receiving support a substantial lead over the 17% European average highlighting the country’s prominence in niche aerospace innovations.
Synergy Among Lithuanian Space-Tech Companies: Blackswan Space’s Autonomous Satellites
Complementing Astrolight’s laser communication, fellow Lithuanian start-up Blackswan Space has developed an autonomous satellite navigation system that enables satellites to self-orient and reposition without continuous ground control intervention. This innovation addresses the challenges posed by the expected surge in satellite numbers, projecting the future impracticality of manual command over thousands of spacecraft.
Tomas Malinauskas, Blackswan Space’s chief commercial officer, detailed the defence potential of their technology, noting applications ranging from targeted neutralization of hostile satellites to advanced battlefield simulations for military training.
However, Malinauskas cautioned that domestic government investment in space technologies has not yet matched the sector’s innovation pace. “Instead of spending $300 million on a single US-made drone, Lithuania could invest in a constellation of small satellites. This approach would offer sustainable, long-term benefits for communication and intelligence gathering,” he stated.
Government Support and Future Directions for Lithuania’s Space Sector
Eglė Elena Šataitė, head of Space Hub LT Lithuania’s government-backed agency supporting space companies acknowledged the government’s awareness of the security landscape and the critical role of space technologies in national defence.
“We recognize that investments in space technology directly enable our defence capabilities,” Šataitė affirmed, underlining the strategic importance of fostering innovation in this sector.
Lukas Savickas, Lithuania’s Minister for Economy and Innovation, echoed these sentiments. “Space technology drives high-value innovation that intersects with biotech, artificial intelligence, optics, and ICT,” he said. “Coordinating investments in these futuristic technologies will further reinforce Lithuania’s economic and security posture.”
Building a Geopolitical and Technological Identity on the World Stage
Lithuanian firms in the aerospace and defence sectors are acutely aware of their geopolitical responsibilities. Dominykas Milasius, co-founder of Delta Biosciences currently developing radiation-resistant medical compounds with potential space and defence applications emphasized this connection.
“Everything we do is intertwined with geopolitics. To earn our place on the global stage, we must deliver critical technologies that compel our allies to invest in Lithuania’s security,” Milasius explained.
This determination among Lithuanian innovators, coupled with growing government support and EU funding, positions the Baltic nation as a formidable player in the evolving global space and defence technology arena.
Analysis and Broader Implications
The advances by Lithuanian companies such as Astrolight and Blackswan Space exemplify how smaller nations can leverage niche technologies to amplify their strategic influence. By developing dual-use space capabilities, Lithuania is enhancing its defence readiness while establishing commercial footholds in a rapidly expanding global market.
Experts suggest that laser-based satellite communications could address increasing bandwidth demand while mitigating cybersecurity risks inherent in RF systems. As satellite constellations become more complex, autonomous navigation systems like those developed by Blackswan Space will be crucial for maintaining effective satellite fleet operations.
“Technologies combining speed, security, and autonomy have significant ramifications for intelligence, surveillance, and reconnaissance missions,” says Dr. Anna Koval, a space systems analyst at the European Space Policy Institute. “Lithuania’s focus on these areas aligns well with NATO’s strategic interests on its eastern flank.”
The coming years will also test how government funding priorities evolve to sustain innovation while balancing short-term defence procurement needs with longer-term technological sovereignty.
Looking Ahead: Lithuania’s Space-Tech Sector on the Rise
Lithuania’s success in space-tech innovation underscores the potential of small nations to influence high-tech domains critical to national security and economic growth. Continued collaboration among industry players, government agencies, and international partners will be essential for maintaining momentum.
As the global satellite landscape grows exponentially, technologies like Astrolight’s lasers and Blackswan Space’s autonomous navigation systems could become indispensable assets not only for Lithuania but across the broader NATO alliance and commercial satellite ecosystem.
