Each Hyperion spacecraft will support S-band links for telemetry, tracking, and command and Ka-band links for high-throughput payload data.
Kongsberg Satellite Services has signed a launch contract for the first Hyperion satellites and is targeting initial deployment in late 2027.
The Hyperion mission will extend Kongsberg Satellite Services' global ground network into low Earth orbit to test how an in-orbit relay layer can cut latency and increase contact opportunities for customer spacecraft.
Kongsberg Satellite Services plans to deploy Hyperion on high-performing satellites of around 300 kilograms to provide the power, pointing agility, and communications capacity needed to demonstrate the full HYPER concept at operationally relevant scale.
Hyperion will host multiple customer demonstrations and early testing campaigns to allow operators to explore low-latency relay services and prepare for onboarding to the full commercial HYPER offering.
The Hyperion mission will verify end-to-end data flow from a customer satellite, through Hyperion, and down to ground in near real time while integrating with existing ground infrastructure and mission operations workflows.
Hyperion satellites will transmit to and receive data from customer spacecraft, relay that data through the Hyperion system, and exercise inter-satellite links within the overall architecture.
Arnulf Kjeldsen, EVP Strategy and Technology at Kongsberg Satellite Services, positions Hyperion as a key step to strengthen secure data delivery and give customers more control over when and where their data reaches the ground.
Hyperion is a small, irregular, sponge-like moon whose orbit is locked in resonance with Titan.
Hyperion will support multiple customer demonstrations and early testing campaigns prior to global scaling of the HYPER service.
The Hyperion satellites will support S-band for telemetry, tracking, and command and Ka-band for high-throughput payload data.
Kongsberg Satellite Services unveiled the Hyperion mission at the SmallSat Symposium in Silicon Valley on February 10, 2026.
The Hyperion mission will validate inter-satellite links and seamless integration with Kongsberg Satellite Services’ global ground infrastructure.
Hyperion will deploy high-performing 300 kg-class spacecraft to validate end-to-end data flow through the relay system to the ground.
