Supercomputing Onboard
Waiting on a downlink is a lost opportunity. Sterna's raw computational power lets you act on critical intelligence the instant it’s captured.
Up to 157 TOPS
Deploy the NVIDIA Jetson Orin NX 16GB to achieve a baseline of 100 TOPS in orbit. For power-rich systems, a simple software unlock pushes performance up to a massive 157 TOPS.
Scalable Power (10W–40W)
Tailor your power-to-performance ratio by equipping either a Jetson Orin Nano or NX. Gain granular software control using stable, enforced presets (10W, 15W, 25W, 40W) or build a custom profile to perfectly match your satellite's budget.
Full NVIDIA Ecosystem
Bring the entire NVIDIA software stack—including CUDA, TensorRT, and cuDNN—into orbit. This seamless "lab-to-launch" workflow lets you deploy the exact same AI models developed on Earth directly onto your satellite.
qualified & validated
Uncompromising
Reliability
Sterna is engineered for mission certainty. It has been validated against every extreme, ensuring it doesn't just survive, but thrives.
Launch & Structural Integrity
Launch-Ready
Compatible with Falcon 9, Ariane 6, and Vega-C.
Tested Durability
Survived a 14.14 g RMS random vibration test and 21.25 g quasi-static sine burst, with post-test checkouts confirming 100% operational health.
Thermal Resilience
Operational Range
-20°C to +65°C in the vacuum of space.
TVAC Qualified
Passed non-operational cycles from -40°C to +80°C and operational cycles from -25°C to +70°C.
Radiation Tolerance
System-Wide Qualification
Tested with 200 MeV protons.
Component Reliability
TID tolerance beyond 30 krad(Si) and robust SEE performance (destructive LET threshold of 38 MeV·cm2/mg).
Data Protection
Targeted irradiation testing on critical components like the SSD ensures complete data integrity.
Operate with our SpaceFeather™ Software
Powerful hardware is only half the equation. The SpaceFeather™ software ecosystem provides the functions you need for mission success.
Running on a dedicated chip, our autonomous supervisor integrates hardware and software monitoring to safeguard system integrity. Its streamlined interface ensures reliable command and control, even in off-nominal situations.
Application Framework
Our containerised application framework allows you to manage and update applications directly in orbit. The custom SDK optimises and compresses Docker image updates for maximum efficiency, minimising uplink costs. The framework empowers you to deploy new capabilities and enhance your mission long after launch.
Radiation Shielding Software
To counter radiation-induced events like SEFIs, our system supports hierarchical fault detection, isolation, and recovery (FDIR) across the entire software stack. This multi-layered defence rapidly copes with radiation effects, dramatically reducing system downtime and ensuring high availability purely from software.
