KSAT Launches Hyperion Demonstration Mission for In-Orbit Data Relay

Feb. 10, 2026

Hyperion is a key milestone for HYPER, as we augment KSAT’s global ground network by extending it into space. The mission will demonstrate how relay satellites can function like ground stations in orbit, reducing latency and increasing availability for satellites.

HYPER is KSAT’s response to the growing demand for faster and more resilient access to satellite data. By bringing ground-station capability into Low Earth Orbit, HYPER adds an in-orbit relay layer that complements KSAT’s global ground network. Built on decades of operational experience, the service is intuitive and transparent for customers, if a satellite is compatible with KSATlite, it will also be compatible with HYPER.  

The Hyperion satellites will validate the core concepts of HYPER, including transmitting to and receiving data from customer satellites, relaying data through the Hyperion system, and demonstrating inter-satellite links within the Hyperion architecture. Furthermore, the satellites will validate the end-to-end data flow from customer satellite, through Hyperion, and down to ground in near real-time. Lastly the mission will demonstrate how Hyperion operates seamlessly with existing ground infrastructure and customer workflows.

Hyperion will support S-band for TT&C and Ka-band for high-throughput payload data, ensuring a familiar and transparent experience for customers, just as they are used to with KSATlite. Hyperion will be deployed using high performing ~300 kg class satellites, providing the power, agility and performance needed to demonstrate the full HYPER concept at scale.

This year marks 10 years of KSATlite and its role in shaping modern, automated ground operations, HYPER represents the next step in building on that success. HYPER will leverage the full KSAT global ground network, consisting of several hundred antennas across 40+ sites worldwide, forming a resilient and trusted foundation for in-orbit relay services. 

“In an increasingly complex operational environment, resilience and speed are just as important as coverage. Hyperion is an important step in proving how HYPER will strengthen secure data delivery and give customers greater control over when and where their data reaches the ground.” says Arnulf Kjeldsen, EVP Strategy and Technology at KSAT.

Hyperion will support multiple customer demonstrations and early testing campaigns, allowing KSAT’s customers to explore how the low-latency relay services can enhance their missions, and as onboarding to the full HYPER service. The launch contract for the first satellites is signed, and the Hyperion satellites are targeting launch in late 2027.
