The space avionics architecture standard tailored to the Common Lunar Lander conceptual design

The major avionics requirements for a Space Generic Open Avionics Architecture (SGOAA) and the Artemis Common Lunar Lander (CLL) are summarized. The SGOAA was applied to the Artemis program which included the tailoring of the operations control subsystem, the space data subsystem, the hardware processor requirements, and the processor internal architecture. It is concluded that tailoring the generic data system to the initial functional requirements for CLL system design facilitated the design that met the Artemis requirements.
