Understanding Coordination, Awareness, and Sustainability in Orbit

Space systems increasingly operate as shared, congested infrastructure environments. The rapid growth in satellite deployments, diversity of operators, and reliance on space-based services has transformed orbit into a complex socio-technical system where coordination and information sharing are as critical as sensing and tracking technologies.

Illumulus studies space systems through a systems and sustainability lens, focusing on how technical capability, governance structures, and human coordination interact to shape safety, reliability, and long-term viability in orbit.

From Technical Capability to System Performance

Significant investments have been made in space situational awareness (SSA) technologies, including tracking sensors, catalogs, and analytical tools. Yet persistent challenges remain, including:

• Fragmented information sharing among operators

• Inconsistent or outdated contact and coordination mechanisms

• Limited interoperability across national, commercial, and regional SSA systems

• Misaligned incentives affecting data transparency and cooperation

Illumulus approaches these challenges by examining why system-level coordination breaks down even when technical data exists.

Space Systems as Socio-Technical Infrastructure

Illumulus treats space systems not solely as technical architectures, but as infrastructure systems shaped by institutions, incentives, and governance frameworks.

Our work considers:

• How SSA-relevant information is generated, curated, and communicated

• The roles and responsibilities of public and private actors

• Trust, provenance, and reliability in shared data environments

• Human and organizational decision-making under uncertainty

This perspective complements technical SSA efforts by focusing on the conditions required for information to be actionable in practice.

Relevance to Space Situational Awareness (SSA)

Illumulus contributes to SSA discussions by addressing questions such as:

• What information is most critical for operational coordination versus long-term planning?

• How can information-sharing frameworks be designed to be practical, trusted, and sustainable?

• What non-technical barriers limit effective coordination among satellite operators?

• How do governance and incentive structures influence SSA outcomes?

Rather than advocating specific tools or architectures, Illumulus focuses on frameworks and principles that support implementable solutions across diverse operational contexts.

Sustainability as Operational Continuity

In the space domain, sustainability is fundamentally about maintaining safe and economically viable operations over time.

Illumulus views space sustainability through:

• Operational continuity and risk reduction

• Coordination mechanisms that scale with increasing orbital activity

• Information architectures that support long-term decision-making

• Institutional arrangements that evolve alongside technology

This framing emphasizes sustainability as an operational requirement, not an abstract policy goal.

Illumulus’ Contribution

Illumulus contributes a systems-level, interdisciplinary perspective to space systems challenges by:

• Bridging technical, organizational, and governance considerations

• Applying lessons from other complex infrastructure domains without conflating them

• Supporting practical, implementable approaches to coordination and information sharing

Our work is intended to inform policymakers, operators, and international forums seeking to improve the effectiveness of SSA and space traffic coordination in an increasingly complex orbital environment.
