Orbijoule

Orbijoule designs and builds uninterruptible power supplies for compute running in orbit. Their systems keep GPU and TPU clusters powered through eclipses, millisecond load spikes, and radiation-induced upsets, addressing the unique power challenges of space-based data centers. The product line spans supercapacitor ride-through buffers, eclipse UPS units for single satellites, and stackable systems for large orbital clusters, with triple-redundant battery management for resilience against single-event upsets. Each product is designed to be qualified once and fly on any major launcher. Orbijoule targets the emerging orbital data-center market, serving satellite operators building always-on compute infrastructure in low-Earth orbit, with early deployments planned from 2029.
