Boldly Going, Running Linux in Space
summary
Linux runs core avionics and payloads across hundreds of satellites, claiming 40.5% of active satellites by late 2021 largely from Starlink and Planet Labs; examples include Planet’s Ubuntu x86 Doves with 0.5 TB storage and Ingenuity’s Snapdragon 801 with RT kernel plus a radiation‑hardened FPGA, all using watchdogs, consensus voting and SpaceX triplicate redundancy (3 pairs voting) for reliability. Embedded stacks use Yocto/Buildroot, Cubesat‑scale Debian derivatives and heavy integration testing for OTA updates and failure fallbacks.
