Final answer:
In Mission Tracking mode, the AV waits for the lost comm timer timeout to expire by monitoring its communication with the Command and Control center. It continues with its pre-programmed mission during this time.
Step-by-step explanation:
In Mission Tracking mode, the AV (Autonomous Vehicle) waits for the lost comm timer timeout to expire by monitoring its communication with the Command and Control center. If the AV is unable to establish communication within a specified time, it assumes that the communication is lost and activates the lost comm timer. During this timeout period, the AV typically continues with its pre-programmed mission, following the last known instructions from the Command and Control center.
