SEALSQ Corp collaborated with its satellite subsidiary WISeSat.Space and parent company WISeKey International Holding Ltd. to launch a WISeSat satellite via a SpaceX Falcon 9 Transporter 16 mission, expanding their satellite constellation aimed at providing secure Internet of Things (IoT) and cybersecurity services globally.

The deployment aligns with WISeSat's focus on establishing a resilient and sovereign space-based communications network capable of supporting real-time, low-power connectivity needs. This effort aims to provide increased coverage and data availability for various applications including industrial IoT and critical infrastructure protection.

The satellite integrates software-defined radio technology allowing in-orbit reconfiguration, and improved data-rate communications to support robust and secure data transfer. These capabilities are intended to enhance performance, resilience, and applicability within the existing constellation.

This launch extends WISeSat's infrastructure, including new ground stations in Spain and planned expansions in Switzerland, which contribute to mission monitoring and secure control of the expanding constellation. Future satellite deployments are scheduled to incorporate quantum-safe key distribution for sectors such as energy and transportation.

Carlos Moreira, CEO of SEALSQ, WISeKey, and WISeSat, said, “This successful launch with SpaceX represents a major step forward for WISeSat and for Europe’s capacity to operate sovereign space-based secure communications. The WISeSat constellation is designed to integrate seamlessly with SEALSQ post-quantum chips, ensuring unprecedented levels of trust, privacy, and resilience for the next generation of connected devices.”

The organizations described plans to further integrate post-quantum security technologies, including SEALSQ’s semiconductors and solutions for Public Key Infrastructure (PKI), aiming to safeguard data against quantum computing threats. The satellite platform also supports trusted digital tokens such as SEALCOIN for secure space-to-ground transactions and tokenized services.
