Sophia Space develops modular orbital data-center infrastructure and software for distributed edge computing in space
Sophia Space develops modular orbital data-center infrastructure and software for distributed edge computing in space. Its TILE architecture integrates solar-powered compute and data storage with passive heat radiation, while its software manages fault-tolerant, radiation-aware workloads across satellite nodes. Applications include AI-driven weather forecasting, space domain awareness, and processing satellite data in orbit to reduce downlink requirements.
