Working Group E

Multi-GSaaS Integration for USG Space Missions

Traditional stovepipe ground architectures are costly and slow in responding to dynamic operational needs. Innovation in ground architecture is needed to enhance agility, resilience, and scalability for USG space operations. This working group (WG) will build upon insights generated during the recent panel discussion on “Ground Segment as a Service (GSaaS) for USG Use” at Milcom 2025 by delving deeper into the regulatory and technological enablers of a multi-GSaaS architecture.

The session will explore critical components such as IP-based transport, scalable routing, and high-speed fiber networks, alongside emerging commercial technologies—including phased arrays, digital IF, virtualization, and cloud-based computing—that can transform the operational landscape. Furthermore, the working group will examine the integration of AI-driven orchestration for autonomous network management and threat response, as well as the strategic role of a Government Enterprise Manager in facilitating seamless multi-GSaaS integration. Participants will engage in collaborative discussions to develop actionable strategies that bridge current technological and policy gaps, providing a roadmap for transitioning from traditional stovepipe ground architecture to flexible, software-defined ground infrastructures for USG. Outcome goals include the formulation of integration frameworks, recommendations for accelerated technology adoption, and identification of best practices for future ground system architecture initiatives in support of dynamic USG operational needs.

The WG will commence with updates and a moderated discussion from government and industry panelists on recent activities, challenges, and potential solutions for GSaaS, followed by an engaging working session. During the working session, the workshop participants will break into focus groups to discuss different aspects of regulatory and technology challenges facing multi-GSaaS concept at the present and future. The focus groups will address the following topics and develop recommendations for out-briefing to the general GSAW attendees:

• • • Government Enterprise Manager for Multi-GSaaS Integration
    • Commercial Technology Enablers: Phased Arrays, Digital IF, Virtualization and Cloud-based Computing
    • High-Speed Fiber Networks
    • Security Considerations
    • Standards & Interoperability
    • AI-driven Orchestration (Autonomous network management, optimization, and threat response)
