en.Wedoany.com Reported - WISeSat, the space subsidiary of Swiss WISeKey International Holding Ltd., released its latest business progress update on May 5, 2026, disclosing that it currently has access to 14 satellites in orbit and is collaborating with SEALSQ Corp. (Nasdaq: LAES), a semiconductor and post-quantum technology company also under WISeKey, to advance post-quantum payload development. The ultimate goal of their collaboration is to support a commercialization roadmap named the "Quantum Space Orbital Cloud." The plan involves the gradual deployment of a 100-satellite constellation to provide Quantum Key Distribution, Quantum Random Number Generation, and Post-Quantum Identity services to global enterprises and governments on a subscription basis, with satellites deployed in phases to achieve full operational capability by 2033.
WISeSat has been building its foundation in technology verification and satellite access for several years. The company initiated pilot testing for secure satellite communications in 2021, conducting technology verification on 21 launched low-earth-orbit satellites, including a larger 3U platform launched by a SpaceX rocket to validate secure IoT communication capabilities. Currently, WISeSat maintains access to 14 operational satellites in orbit. On March 30, 2026, WISeSat's 21st satellite was launched into low Earth orbit aboard a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California as part of the Transporter-16 rideshare mission. This satellite carries SEALSQ's QS7001 post-quantum chip to validate critical secure communication technologies. On the ground segment side, the company has ground facilities in Switzerland and Spain to support the construction of command, control, and data distribution architecture.
The roadmap for post-quantum collaboration between WISeSat and SEALSQ is becoming increasingly clear. SEALSQ's post-quantum technology is being integrated into the WISeSat satellite roadmap, covering secure elements, quantum root key functions, and cryptographic capabilities for future satellite generations. The QSOC jointly planned by both parties is a dual-layer architecture of "Infrastructure-as-a-Service plus Cloud Services": WISeSat, as the owner and operator of the satellite constellation, is responsible for satellite design, manufacturing, launch, and mission operations; SEALSQ acts as the operating entity for quantum cloud services, delivering quantum security services directly to government, financial institutions, defense organizations, and enterprise customers. According to service commitments previously announced by SEALSQ, the platform will offer a 99.9% availability Service Level Agreement.
The next major milestone is the transition to the 6U satellite platform. WISeSat's first 6U post-quantum satellite platform is scheduled for launch in November 2026, with the first batch of 15 6U satellites expected to be deployed before 2027, forming the initial elements of the QSOC constellation. This platform will offer greater payload flexibility, longer mission life, and broader application potential. WISeSat has previously completed a pilot phase collaboration with the Swiss Armed Forces Space Command, evaluating technology architecture options, operational concepts, and future government and defense application scenarios, and will continue this collaboration on the next-generation 6U missions.
WISeSat's pace of advancement also reflects the accelerating trend of convergence between the low-earth-orbit satellite industry and post-quantum security concepts. Against the backdrop of urgent demand for quantum-secure communication from AI computing power networks, embedding post-quantum cryptography capabilities directly into the satellite hardware layer and then providing global subscription services in the form of an orbital cloud is moving from proof-of-concept to the engineering implementation phase. Carlos Moreira, Founder and CEO of WISeKey, recently stated: "In just a few years, WISeSat has evolved from its first secure satellite communication pilot mission into a mature space technology roadmap. The company is ready to meet the growing demand for low-earth-orbit quantum-secure infrastructure, providing secure data services, edge processing, and trusted connectivity to government and commercial customers."
