What is guidance navigation control engineering?

Guidance Navigation Control (GNC) Engineering is a specialized field of engineering focused on the design and development of systems that enable vehicles—such as aircraft, spacecraft, missiles, and autonomous vehicles—to navigate and control their movement accurately. GNC engineers work on algorithms and hardware that allow these vehicles to determine their position, plan their path, and execute maneuvers safely and efficiently. This field combines elements of aerospace engineering, control theory, robotics, and computer science to ensure vehicles can reach their destinations reliably, often in complex or dynamic environments.
