EDGX

What EDGX does

EDGX builds products that put compute in orbit, pioneering the next generation of onboard AI technology for space. They provide the compute layer of the space economy, shifting intelligence from Earth to orbit with their AI computers. Their products are designed for mission-critical decisions in real-time, enabling satellites to deliver insights rather than just data. EDGX focuses on providing reliable, high-quality, and scalable in-orbit compute solutions for various space missions.

Products

• SternaA flight-proven, space-hardened AI edge computer for satellites, designed to power ambitious payloads and enable real-time, in-orbit decisions. It offers supercomputing capabilities with up to 157 TOPS, scalable power, and full NVIDIA ecosystem compatibility. Sterna is engineered for mission certainty with rigorous testing for launch & structural integrity, thermal resilience, and radiation tolerance. It integrates with SpaceFeather™ software for mission success.
• SpaceFeather™ SoftwareAn ecosystem of software functions for mission success, running on Sterna. It includes a space-hardened Linux OS, a minimal Yocto build, rigorous traceability, and JetPack 6 compatibility. It features an autonomous supervisor for system integrity and a containerized application framework for in-orbit application management and updates. It also includes radiation shielding software for hierarchical fault detection, isolation, and recovery (FDIR).
