Dutch Scientists Develop Revolutionary Laser Technology to Triple Satellite Internet Speeds
Delft, Wednesday, 21 January 2026.
TU Delft researchers secured major funding to create breakthrough satellite communication technology using multiple laser beams that combine in space for unprecedented data transmission rates. The innovative STARS project tackles atmospheric interference with advanced modulation techniques, potentially revolutionizing global telecommunications and strengthening strategic digital autonomy amid rising geopolitical tensions.
NWO Funding Breakthrough Announced Monday
On January 20, 2026, Dr. Rudolf Saathof of Delft University of Technology received funding from the Netherlands Organisation for Scientific Research (NWO) through the Dutch National Growth Fund programme NXTGEN Hightech [1]. The research project, officially titled “STARS: Smart 3D Tomographic Adaptive Optics for a Turbulence-Resilient Optical Communications System,” aims to enable very high data rates for geostationary telecommunications satellites [1]. This funding represents part of a broader €14 million allocation announced on January 8, 2026, supporting eight consortia developing next-generation high-tech equipment [2].
The Technology Behind STARS
The STARS project develops an innovative system that combines multiple laser beams to create high optical intensity at the satellite’s location, significantly strengthening the signal [1]. This approach is essential for achieving high data speeds and reliable communication over the vast distances to geostationary satellites, which orbit approximately 35,786 kilometers above Earth [GPT]. The system addresses a fundamental challenge in satellite communications: geostationary satellites are ideal for data transmission because they move at the same speed as Earth’s rotation, making them easy to track from ground stations, but their great distance from Earth places high demands on signal strength and reliability [1].
Overcoming Atmospheric Interference
Advanced modulation techniques form a critical component of the STARS system, designed to cope with disturbances caused by Earth’s atmosphere [1]. Laser communication utilizes light signals, but these signals are weakened in the atmosphere through interaction with air molecules and disrupted by turbulence [1]. The intelligent, advanced modulation can transmit more data per second, better handle noise and interference, and recognize and correct errors [1]. This technological approach represents a significant advancement over current satellite communication methods, which often struggle with atmospheric interference that degrades signal quality and reduces data transmission rates [GPT].
Research Team and Strategic Implications
The research team includes Dr. Saathof, Dr. Carlas Smith from TU Delft’s Faculty of Mechanical Engineering, Prof. Chigo Okonkwo from Eindhoven University of Technology, and Thomas Dreischer from Airbus [1][6]. Dr. Saathof emphasized the strategic importance of this research, stating: “Reliable and secure communication is more important than ever, especially at a time of increasing geopolitical tensions. With this research, we aim to develop unique technology for optical satellite communication that enables higher data rates and strengthens strategic autonomy” [1]. The developed technology specifically aims to strengthen strategic autonomy in optical satellite communication, addressing growing concerns about digital infrastructure independence [1].
Testing and Implementation Timeline
The research methodology combines theoretical modeling with experimental laboratory tests, followed by outdoor testing where laser beams will be transmitted through the actual atmosphere to expose the system to realistic disturbances [1]. Prof. Chigo Okonkwo and Thomas Dreischer are collaborating on combining theoretical modeling with experimental laboratory tests [1]. The outdoor testing phase will follow laboratory work, involving laser beams transmitted through the atmosphere to validate the system’s performance under real-world conditions [1]. This comprehensive testing approach ensures the technology will perform reliably when deployed for actual satellite communications applications [GPT].
