Which MC is responsible for Navigation?

• A. MC2
• B. MC1
• C. Both
• D. None

Answer: (B)

Navigation is handled by the primary mission computer because it needs to run the essential state estimation and path calculations with the highest priority and a consistent data flow. In a dual-MC setup, the primary computer (MC1) is designated to run the navigation algorithms, fuse sensor data from IMUs and other inputs, and produce the guidance state used by the rest of the system. The other computer (MC2) typically serves as a backup or takes on non-navigation tasks, stepping in if MC1 fails but not serving as the main source of navigation outputs. So, the navigation function is assigned to MC1 rather than MC2, both, or none.
