About
We are pioneering the next generation of spacecraft avionics with our new Onboard Computer (OBC) built around Microchip’s cutting-edge PIC64 architecture. As an official Microchip Design Partner and a participant in the High-Performance Spaceflight Computing (HPSC) program, we benefit from early access to PIC64 technology—allowing us to engineer a robust, radiation-tolerant, and high-performance OBC platform designed for the most demanding space missions. Our mission is simple: deliver reliable, intelligent, and future-proof onboard computing capabilities for modern spacecraft and aerospace systems.
