Guidance, navigation, and control (GNC)

Guidance, Navigation, and Control (GNC) refers to the systems that help vehicles, like rockets, drones, or spacecraft, reach their destinations safely and accurately. "Guidance" determines the best path to take, "navigation" involves figuring out where the vehicle is at any moment, and "control" manages the vehicle's movements to follow the chosen path. Together, these systems ensure that the vehicle can not only get to its target but also respond to changes or obstacles along the way, much like how a driver uses a map and steering to reach a destination.
