WISeKey’s WISeSat and Spacetalk Forge Strategic Partnership for Global Space Traffic Coordination

Davos, January 21, 2026 — WISeKey International Holding Ltd (“WISeKey”), a global leader in cybersecurity, blockchain, and Internet of Things (IoT) technologies, announced today that its space-focused subsidiary, WISeSat.Space (“WISeSat”), has signed a memorandum of understanding (MoU) with Spacetalk SA, a Swiss company creating a neutral, transparent, and collaborative digital platform dedicated to global space traffic coordination.

Addressing the Growing Challenges in Space Traffic Management

The rapid increase in satellite deployments, the accumulation of space debris, and the absence of a unified international framework for space situational awareness and traffic management have made orbital activities more complex and potentially hazardous. Traditional approaches remain fragmented, often relying on national systems or bilateral agreements that do not fully address the risks associated with a congested orbital environment.

In response, Spacetalk has developed a voluntary, neutral platform aimed at enabling secure and trusted collaboration among civil, commercial, institutional, and academic space actors. WISeSat’s role in this partnership is to bring secure access and trusted digital identity verification to the platform using WISeKey’s WISeID services, creating a reliable environment for data exchange and coordination.

The Strategic MoU: First Step Toward Operational Collaboration

The MoU signed between WISeSat and Spacetalk marks an initial yet significant step toward a strategic partnership that will support the operation of this neutral global space traffic coordination platform. Spacetalk’s solution is designed to provide a transparent, non-discriminatory environment where space operators can share orbital data, coordinate maneuvers, and enhance overall space safety.

WISeSat will contribute its expertise in secure satellite communications and digital identity management, ensuring that only authenticated and authorized stakeholders, verified through rigorous Know Your Customer (KYC) processes, can access sensitive operational data. This emphasis on identity and data integrity is intended to promote trust and accountability among platform users.

Key Features and Functionality of the Platform

The collaborative platform will offer various advanced capabilities to participating stakeholders:

• Secure Data Sharing — Authorized users can exchange orbital and trajectory data in a trusted environment.
• Interoperability Tools — The platform supports conversion between different orbital data formats, such as Two-Line Elements (TLE) and Orbital Ephemeris Messages (OEM), enabling coordination among diverse systems.
• Inventory and Directory Access — Participants can view a comprehensive inventory of space objects and an up-to-date directory of stakeholders engaged in space operations.
• Secure Messaging — A dedicated secure communication channel allows targeted, protected messaging between operators, independent of national systems.

Pilot Phase Success and Global Participation

During a pilot phase conducted in October 2025, institutional, industrial, and academic partners from around the world tested the platform’s secure access and data interoperability features. Participants included prominent organizations such as the European Space Agency (ESA), Okapi Orbits, EPFL, the Swiss Armed Forces, Chinese space tech firm Debris-X, and Indian space entity OrbitArch. This diverse participation demonstrated the platform’s ability to support collaboration across different regions and institutional profiles.

Leadership Perspectives on Space Safety and Collaboration

Dr. Benjamin Guyot, Founder and CEO of Spacetalk, highlighted the importance of the pilot’s success, emphasizing that the neutral and voluntary nature of the platform accelerates practical solutions for space safety without waiting for broader international political consensus.

Carlos Moreira, CEO of WISeKey, added that the pilot demonstrated the value of trusted, interoperable data sharing for operational space safety and that WISeSat’s expertise helps lay the foundation for global coordination on space traffic management.
