About
LizzieSat is a highly adaptable, software-defined satellite bus platform supporting Earth observation, in-orbit demonstrations, technology validation, and microgravity and radiation research, at technology readiness level 9 with flight heritage across three launched units: LS-1, LS-2, and LS-3. The platform is designed for 3, 5, or 7-year mission life with simultaneous multi-sensor data collection, including multispectral, AIS, and optical, and near-real-time AI edge processing via the Orlaith ecosystem.
