SPEL and the SCY-FI Lab maintain and evolve the SUCHAI Flight Software, a framework that has already flown several missions and remains central to both groups’ aerospace research. It is hardware-agnostic, with ports to the Nanomind A3200, Raspberry Pi, ESP32 and STM32 processors, and its code is fully open source for audit and reuse. Current work covers state sharing across distributed onboard computers, unified SIL and HIL testing interfaces, hardening of space assets against modern threats, and continuous code quality and performance refinement.
