What system acts as the brain for precision-guided munitions (PGM)?

The guidance system is essential for precision-guided munitions (PGM) as it directs the munitions towards their intended target with a high level of accuracy. This system processes information about the target and the vehicle's position and trajectory, allowing for real-time adjustments and corrections during flight. By utilizing various sensors and algorithms, the guidance system ensures that the munition can navigate effectively, making autonomous adjustments to account for factors such as wind, speed, and distance to the target. Without the guidance system, PGMs would not achieve the precision that defines them, relying instead on less accurate and more traditional forms of delivery.
