In the two-MC system, what are the defined roles for MC1 and MC2?

• A. MC1 Navigation; MC2 Mission Accomplishment
• B. MC1 Mission Accomplishment; MC2 Navigation
• C. MC1 Navigation; MC2 Navigation
• D. MC1 Mission Accomplishment; MC2 Mission Accomplishment

Answer: (A)

In this two-MC setup, responsibilities are divided to keep navigation data separate from mission execution tasks. One computer is dedicated to navigation—calculating position, velocity, routes, and providing guidance data—while the other is dedicated to mission accomplishment—carrying out mission objectives, controlling payloads, and ensuring tasks are completed. This separation enhances reliability because each computer focuses on a distinct, critical function and can cross-check the other's outputs. Therefore, the defined roles are MC1 for navigation and MC2 for mission accomplishment. Swapping roles or duplicating both functions on both machines would undermine this separation and reduce robustness.
