Intelligent and autonomous systems refer to machines or devices that can perform tasks or make decisions without human intervention. These systems use advanced technologies such as artificial intelligence, machine learning, and robotics to analyze data, identify patterns, and make predictions. Guidance, Navigation, and Control (GNC) is an essential component of intelligent and autonomous systems, providing the ability to navigate and control the system's movement. GNC systems use sensors and algorithms to gather and process information about the environment, making adjustments to the system's trajectory or behaviour in response to changing conditions. Intelligent and autonomous systems with GNC have a wide range of applications, from self-driving cars to unmanned aerial vehicles, making them increasingly important in today's world.
