Targeting the commercial and defense bottlenecks of legacy radio frequency (RF) networks, Lithuanian laser technology developer Astrolight has outlined a strategic framework calling on European policymakers to scale optical communications.
The firm warns that while Europe is currently investing billions in sovereign space systems, establishing true autonomy requires an industrialized optical data layer to keep pace with foreign mega-constellations.
Comparison of Optical vs. Radio Frequency Communication
To bypass the licensing delays and congestion of traditional RF architectures, Astrolight is advocating for a rapid industrial transition to laser-based terminal payloads:
| Architectural Metric | Traditional Radio Frequency (RF) | Optical (Laser) Communications |
| Data Transmission Rate | Baseline speeds; highly susceptible to bandwidth congestion. | Up to 100 times higher data throughput. |
| Physical Beam Profile | Broad, dispersive signal footprint. | Narrow, highly focused pencil-thin light beams. |
| Security & Intercept Risk | Vulnerable to terrestrial jamming and remote interception. | Highly resistant to detection, spoofing, and electronic jamming. |
| Regulatory Hurdles | Severe spectrum licensing bottlenecks and coordination delays. | Operates outside congested ITU radio frequency allocations. |
European Sovereign Infrastructure Context
The push to deploy optical infrastructure aligns with several major continental initiatives aimed at reducing reliance on foreign space services. These include the development of the EU’s flagship IRIS² secure satellite constellation, the European Space Agency’s (ESA) multi-orbit HydRON transport network, and Germany’s proposed €35 billion defense space modernization initiative.
However, Astrolight executives stress that institutional space programs must be matched by a robust commercial manufacturing ecosystem.
“If Starlink remains the only widely available commercial space network using optical communications, European operators will inevitably turn to it for superior speeds and data security,” said Laurynas Mačiulis, CEO of Astrolight. “Optical data transfer stopped being a next-gen technology for specialized missions and is now becoming a matter of strategic and market advantage.”
According to market projections by Novaspace, global satellite connectivity demand is expected to expand more than 11-fold between 2024 and 2034, making space-to-ground downlink speed a critical operational bottleneck.
Scaling the Optical Industrial Layer
To bridge the gap between flagship programs and commercial execution, Astrolight is calling for the rapid industrialization of proliferated inter-satellite optical links, ground telescope receiver terminals, and standardized user segments. This push builds directly on the company’s recent technical milestones, including its partnership with Kepler Communications to develop the user-terminal segment for ESA’s HydRON Element 3 utilizing its proprietary ATLAS-X laser terminal, alongside the commissioning of the Holomondas Optical Ground Station in Greece.
By scaling these modular, vertically integrated laser communication systems, European operators can secure a highly competitive, sovereign alternative to non-European space connectivity providers.
