The partnership between the ESA and CTO see Europe’s first 5G mmWave system launched and tested from a satellite in LEO. The project tries to counter the biggest positions in satellite networking by unveiling a 5G system made in Europe on a satellite slated for launch in June 2025. The “Early Test” ensures communication between space-based infrastructure and today’s ground-based 5G systems, opening up new high-speed, low-latency options for global connectivity.

This cooperation is in keeping with Europe’s wider efforts to become independent in the digital sector and support innovation. Experimental equipment from ESA’s ECSAT site in Oxfordshire will assist the campaign. Achieving this project’s goals could change European space telecommunications and give worldwide operators a reasonably priced, independent alternative to current mega-constellations.

Key Highlights

• Europe’s First 5G Satellite Test: A regenerative 5G mmWave payload will be launched into LEO in June 2025 as part of real-world testing.
• Space + Earth Network Integration: The test aims to show how satellite networks can work smoothly with existing ground-based 5G systems.
• Designed and Built in Europe: The technology is entirely European-made, supporting the EU's vision of tech independence and innovation.
• Cost-Effective Alternative: Offers a competitive, independent option against American and Chinese satellite giants—ideal for global telecom providers.

Statements Of Industry Leader

Charles Delfieux, CEO & Founder of CTO

"This alliance with ESA reflects a shared ambition: to build a competitive European sovereignty in space connectivity, powered by bold technology designed and developed in Europe. We’re proving that it’s possible to compete on a global scale without compromise—giving telecom operators back control over their future in space. Space is the new frontier for telecoms!"

Laurent Jaffart, Director of Connectivity and Secure Communications at ESA

"This agreement aligns with ESA’s strategy to support the rise of innovative European players and jointly build resilient connectivity. The upcoming tests with CTO will pave the way for new hybrid use cases at the intersection of terrestrial and space networks."
