OneWeb LEO Constellation
Overview
Low Earth orbit broadband constellation providing global coverage through a Gen 1 fleet of 654 satellites at roughly 1,200 km altitude. The network delivers 1.1 Tbps of sellable capacity, sub-70 ms latency, and 99%+ availability, and is integrated with Eutelsat's GEO assets for multi-orbit services across government, mobility, enterprise, and telecom markets. The follow-on satellite program now covers 440 Airbus-built spacecraft, adding upgraded onboard processing and hosted-payload options while maintaining service continuity.
Gen 1 is fully deployed and commercially operational. Eutelsat has procured 440 follow-on satellites, with 100 planned by 2027 and the remaining 340 by 2029, alongside additional satellite-network portals, hosted payloads, and a broader 5G-compatible user-terminal rollout.
