Key highlights

The EDGX Sterna DPU is the most optimal earth-like AI processing system hardened to scale in space. Powered by NVIDIA Jetson Orin NX technology, this DPU is designed for powerful, energy-efficient and scalable onboard AI computing for smallsats.

A built-in supervisory system improves reliability and availability through real-time monitoring and automated recovery. The DPU supports flexible power mode configuration, allowing users to adapt power consumption to mission constraints. Designed for ease of development, it features a Docker-based application deployment framework and is reprogrammable through reliable over-the-air (OTA) updates. Qualified for radiation, thermal, mechanical, and electromagnetic conditions, the compact and efficient DPU integrates seamlessly into a wide range of satellite platforms and supports all common European and U.S.-based launch vehicles.
