SES Accelerates Multi-Orbit IFC Strategy with meoSphere and Next-Gen ESA Development

Why It Matters

By unifying multiple orbital layers, SES offers airlines and sovereign users high‑capacity, low‑latency connectivity that rivals integrated constellations like Starlink, opening new revenue streams in B2B and B2G markets.

Key Takeaways

• SES plans 28 high‑power MEO satellites for meoSphere.
• New flat‑panel ESAs enable 1 Gbps per aircraft across orbits.
• Multi‑orbit antennas support simultaneous MEO and LEO connectivity.
• Pathfinder launches start 2028, full service targeted for 2030.
• meoSphere targets B2B/B2G markets, competing with Starlink.

Pulse Analysis

The in‑flight connectivity (IFC) landscape is rapidly evolving as airlines, defense agencies, and maritime operators demand uninterrupted, high‑throughput links. Traditional geostationary (GEO) satellites have struggled with latency and coverage gaps, prompting a shift toward low‑Earth‑orbit (LEO) constellations that excel in speed but require dense networks. SES, a veteran satellite operator, is positioning itself at the intersection of these trends with its multi‑orbit strategy, leveraging Medium Earth Orbit (MEO) to combine GEO’s wide‑area efficiency and LEO’s low latency. The meoSphere initiative embodies this hybrid approach.

The core of meoSphere is a 28‑satellite constellation built on K2 Space’s high‑power bus, delivering roughly 20 kW per spacecraft—about twice the power of earlier MEO platforms. This surplus enables digital regenerative payloads and software‑defined beamforming that can dynamically allocate capacity to high‑traffic corridors. On the ground, SES is standardizing two flat‑panel electronically steered antenna (ESA) sizes, 25 × 25 cm and 50 × 50 cm, capable of tracking multiple satellites across MEO, GEO and LEO simultaneously. The result is a promised 1 Gbps per aircraft link with seamless handover between orbital layers.

From a commercial perspective, the multi‑orbit architecture opens lucrative B2B and B2G opportunities where reliability and bandwidth are mission‑critical. Early‑adopter governments and premium airlines can access a resilient network that does not rely on a single constellation, differentiating SES from vertically integrated rivals such as SpaceX’s Starlink. The company has folded meoSphere into its 2026 capital‑expenditure plan, targeting pathfinder launches by 2028 and full service by 2030. If the technology scales as projected, SES could capture a significant share of the $15‑20 billion global IFC market.
