About

Colossus Computing builds radiation-tolerant, AI-capable edge computing hardware and software for spacecraft, so satellites can process sensor data in orbit instead of downlinking it raw. Its product line spans GPU compute boards, an FPGA/DSP platform, a gigabit Ethernet switch, and computational storage, paired with an open-source Linux-based operating system. Its Kestrel processor reached flight heritage aboard Loft Orbital's YAM-6 satellite. The company was formerly named Zephyr Computing Systems and is backed by NASA SBIR Phase I and II awards and Space Development Agency work.

Fault-tolerant, self-healing architecture with ECC-protected memory and redundant CPUs that survives orbital radiation while delivering GPU-class AI performance, sold as developer-ready hardware plus an open-source OS rather than a bespoke avionics program.
