While the missile is in flight, the Global Positioning System receiver/processor updates the missile1s inertial navigation system. This helps to ensure that the missile's imaging infrared seeker is pointed directly at the target. When the infrared seeker is activated, it sends a video image to the pilot, who selects a specific aimpoint on the target. After the pilot locks the seeker onto the target, the missile makes an autonomous precision strike that minimizes damage to surrounding areas.
