SES has announced a significant step in the development of its future Medium Earth Orbit (MEO) satellite network. On March 24, 2026, the company revealed plans to deploy meoSphere, a next-generation satellite constellation expected to be operational by 2030. The initial phase will integrate SES’s software-defined payloads, developed and manufactured in Luxembourg, with 28 high-power satellite platforms from K2 Space. This marks the first deployment phase of the broader meoSphere rollout.
Strategic Importance of meoSphere
This announcement represents more than just an expansion of SES’s satellite fleet. It signifies a transformative step in SES’s growth strategy for MEO connectivity. According to SES, meoSphere is designed to enhance MEO network capacity, improve user data speeds, reduce terminal size and costs, and cater to government, mobility, and fixed telecommunications markets. Additionally, the system will be compatible with Europe’s IRIS2 program, reinforcing its strategic role in sovereign and institutional communications.
Key Deployment Architecture
The architecture of the satellite deployment is a critical aspect of the announcement. SES plans to deploy 28 satellites in the first phase, arranged in four inclined orbital planes, with seven satellites per plane, operating at approximately 8,000 km altitude to provide global pole-to-pole coverage. Each satellite is expected to deliver 20 kW of power, an improvement over the previous generation. The network will feature optical intersatellite links, hosted-payload flexibility, onboard computing and storage, and compliance with 5G-NTN and 3GPP standards, enabling seamless integration with terrestrial and multi-orbit networks.
Multi-Mission Capabilities
SES envisions meoSphere as more than a traditional broadband-focused constellation. The network is being designed as a multi-mission MEO platform capable of supporting broadband connectivity, sovereign networking, hosted payloads, space situational awareness, optical relay, and data relay between orbital systems. This positions meoSphere as a versatile orbital infrastructure layer for both commercial and government customers.
Innovative Deployment Strategy
The deployment strategy reflects a shift in how satellite systems are developed. Over the next three years, SES plans to conduct a series of MEO pathfinder missions with K2 Space to test satellite bus and payload components in orbit, refine operational concepts, and mitigate risks before full-scale deployment. This approach builds on the companies’ September 2025 collaboration, which emphasized an iterative, agile development model over the traditional “waterfall” approach.
Broader Context and Roadmap
This announcement aligns with SES’s broader MEO roadmap. Earlier this month, SES reported that 10 of its 13 O3b mPOWER satellites had been launched, with the remaining three scheduled for the second half of 2026. MeoSphere is designed to complement this existing infrastructure, adding capacity, resilience, and mission flexibility to meet growing demand across broadband, defense, aviation, maritime, and telecommunications applications.
Why This Announcement is Significant
This next-generation satellite constellation announcement stands out for integrating three key themes: higher-power satellites, software-defined MEO networking, and a deployment model focused on faster scaling. If SES adheres to its timeline, meoSphere could become one of the most closely monitored MEO satellite deployment programs of the decade, offering low-latency connectivity, resilient sovereign communications, and multi-mission orbital infrastructure for a wide range of customers.
