WISeKey, a leading global cybersecurity, blockchain, and IoT company, announces that its subsidiary, WISeSat, an entity that focuses on space technology for secure satellite communication, specifically for IoT applications, and Spacetalk, a company developing the world’s first neutral, transparent, and collaborative digital platform dedicated to global space traffic coordination, signed an MoU as 1st step for preparing a strategic partnership to operate an innovative and neutral platform dedicated to global space traffic coordination.
In response to the absence of a unified international framework and the exponential growth in the number of satellites and space actors, Spacetalk offers a transparent, collaborative, and non-discriminatory solution aimed at preventing collisions, avoiding conflicts, reducing space debris, ensuring equitable access to space, and preserving the freedom to observe the universe.
WISeSat complements this initiative by providing secure and trusted access to the Spacetalk platform through the use of personal digital identities issued via WISeKey’s WISeID services. These identities are delivered following a rigorous identity verification process (KYC – Know Your Customer), ensuring that only duly identified, authenticated, and authorised actors can access the platform. This approach enables space traffic operators and stakeholders to coordinate maneuvers and exchange critical information within a highly reliable, traceable, and sovereign environment. Open to all global space actors, from civil, to institutional, commercial, and academic, the Spacetalk platform operated in partnership with WISeSat, aims to foster operational dialogue and secure information sharing in order to address the urgent and growing challenges of space traffic management (STM).
As the orbital environment becomes increasingly congested, driven by the rapid expansion of satellite constellations, the accelerated accumulation of space debris, and the lack of coordinated international regulation, management of orbital activities remains fragmented and largely dependent on national systems and ad hoc bilateral agreements. This lack of coordination elevates collision risks, drives up operational costs associated with avoidance maneuvers, and fuels misunderstandings among civil, commercial, and military space actors. Spacetalk addresses these challenges by providing a neutral and collaborative platform designed to establish continuous operational dialogue and facilitate the sharing of essential information among stakeholders, including between competing spacefaring nations.
During the pilot phase conducted in October 2025, institutional, industrial, and academic partners accessed the Spacetalk platform through a secure and personalised authentication process based on certified digital identities. Participants shared orbital data on space objects with other platform members in an environment designed to ensure confidentiality, traceability, and interoperability of exchanges. They also used Spacetalk’s advanced orbital data conversion tools, developed in collaboration with partners, to translate existing formats, particularly Two-Line Elements (TLE) and Orbital Ephemeris Messages (OEM), into a common format enabling cooperation across heterogeneous systems.
This testing phase also allowed users to access the platform’s inventory of space objects as well as its stakeholder directory, significantly improving space situational awareness and the understanding of the actor landscape. Interactions were further supported by a dedicated secure messaging system, providing a direct, targeted, and protected communication channel among members, independent of any national infrastructure. Partners participating in the pilot represented the world’s major space regions: in Europe, the European Space Agency (ESA), Okapi Orbits, EPFL, and the Swiss Armed Forces and in Asia, Chinese entities such as Debris-X, as well as Indian partners like OrbitArch. This geographical and institutional diversity highlights the ability of Spacetalk and WISeSat to bring together stakeholders with highly diverse profiles within a common framework for voluntary, neutral, and trust-based dialogue.
“After a very successful testing phase, we are extremely proud to launch Spacetalk with WISeSat and to open our platform to all global space traffic actors,” said Dr. Benjamin Guyot, Founder and CEO of Spacetalk. “Spacetalk is an accelerator of concrete solutions for space safety. Our voluntary and neutral approach enables immediate and pragmatic action, without waiting for an international political consensus.”
“The Spacetalk pilot demonstrated the value of trusted, interoperable data-sharing for operational space safety,” said Carlos Moreira, CEO of WISeKey. “By contributing WISeSat’s expertise and operational perspective, we are helping lay the foundation for practical, collaborative space traffic coordination at a global scale.”
