Which component provides location to the MIDS to support the PPLI function and also provides timing?

• A. Mission Computer
• B. Audio Management Computer
• C. EGIs
• D. Crypto Load Panel

Answer: (C)

PPLI uses precise position and timing information, so the system that supplies accurate location data and synchronized time to the MIDS is the navigation subsystem. The Embedded GPS/Inertial (EGI) combines GPS positioning with inertial navigation to produce a precise location and exact timing. That nav data is fed to the MIDS to support the PPLI function, allowing transmissions to carry a trusted position and timestamp for other participants to reference. The other components focus on mission processing, audio, or cryptographic keys and do not provide nav position or timing data to the MIDS. So the EGIs are the source of both location and timing for PPLI.
