The data bottleneck for satellite operators is not processing power or storage. It is getting the data to the ground fast enough to matter.
Dr. Jordan Vannitsen is the Co-founder and CEO of Odysseus Space, a Luxembourg-based company developing laser communication solutions for space-to-ground data transfer. Founded in 2019, the company has built a team with over 100 years of combined experience in lasers, optics, and space systems. Vannitsen’s focus is delivering end-to-end optical communication services that simplify the data transfer chain for satellite operators who need high-performance, reliable, and secured connectivity.
The company’s flagship product, Cyclops, is a laser communication terminal designed to deliver up to 10 Gbps and 1 terabyte per day through a network of optical ground stations. The system is approaching its first in-orbit validation: a LEO-to-ground link demonstration in partnership with Berlin-based Reflex Aerospace, with the first commercial space-to-ground mission planned for late 2026. Intersatellite link capability is targeted for 2027. The European optical communications landscape includes established players like Mynaric and Cailabs alongside newer entrants, and the competitive field is moving fast as defense and institutional demand for secure, high-bandwidth links accelerates.
Vannitsen has argued that laser communication is the infrastructure layer that will transform isolated satellite constellations into connected, distributed computing systems. In a March 2026 analysis for SatNews, he examined the intersection of laser communications and the rise of orbital data centers, making the case that the compute-in-orbit thesis depends on optical links that do not yet exist at scale. SatNews has tracked the broader optical comms field through its coverage of the next generation of space networks at SmallSat Europe 2025.
At SmallSat Europe, Vannitsen joins the panel “Quantum-Ready Constellations: Optical Comms and QKD for Unhackable Links,” alongside Cailabs CEO Jean-François Morizur, SES Space & Defense’s Philippe Glaesener, and Thierry Draus. The session explores the timeline and technological milestones required to secure Europe’s orbital infrastructure against future quantum computing threats through optical communications and Quantum Key Distribution.
The quantum threat to encrypted satellite links is theoretical today. The infrastructure to defend against it has to be built now.
