LUXEMBOURG — Commercial satellite operator SES has secured airline contracts with Finland’s flag carrier Finnair and Kazakhstan’s Air Astana to deploy multi-orbit in-flight connectivity (IFC) services across their passenger fleets, Via Satellite reported on Tuesday, Nov. 3, 2026.
Under the agreements, both carriers will integrate SES’s hybrid architecture combining geostationary Earth orbit (GEO) satellites with the O3b mPOWER medium Earth orbit (MEO) constellation.
Multi-Orbit Network Architecture and Latency Performance
The dual-orbit service pairs high-capacity GEO wide-beam and spot-beam assets with low-latency MEO throughput. By routing passenger traffic across both orbital tiers, the architecture delivers broadband data transit designed to minimize latency bottlenecks common to legacy single-orbit aviation links.
The service relies on the O3b mPOWER MEO constellation, which operates at an altitude of approximately 8,000 kilometers. Operating in the Ka-band, the software-defined Boeing 702X satellites utilize electronically steered phased-array antennas capable of dynamically generating and steering thousands of spot beams. This agility allows SES to dynamically assign dedicated gigabit-level capacity to aircraft as they traverse high-traffic European and Central Asian air transit corridors.
Aviation Market Expansion Across Nordic and Central Asian Routes
The selection of SES by Finnair and Air Astana highlights the accelerating commercial shift away from single-orbit networks toward hybrid constellations. As passenger demand for high-bandwidth streaming, real-time gaming, and cloud-based workplace applications grows at cruising altitudes, regional and international airlines are seeking connectivity architectures that offer resilient failover and global route coverage.
The dual-carrier win also expands SES’s operational presence across distinct geographic operating environments, extending MEO-supported connectivity to Finnair’s northern polar and transcontinental routes connecting Europe to Asia and North America, while establishing high-throughput commercial aviation coverage across Air Astana’s domestic and international Eurasian network.
Commercial Terms and Fleet Implementation Milestones
While financial details, total aircraft installation counts, and specific entry-into-service schedules were not disclosed in initial reporting, the agreements advance the operator’s broader multi-orbit in-flight connectivity strategy. Implementation across both airlines’ fleets will progress through line-fit and retrofit installations of compatible multi-band fuselage terminals and onboard distribution systems as deployment programs get underway.
