Guidance systems are technologies designed to assist in navigation and control of vehicles, whether they are aircraft, ships, or ground vehicles. These systems use various methods, such as GPS, inertial navigation, and sensors, to determine the position and direction of the vehicle. They help ensure safe and efficient travel by providing real-time information and adjustments. In military applications, guidance systems are crucial for precision targeting of weapons like missiles and drones. They often incorporate advanced algorithms and data from multiple sources to enhance accuracy. Examples of guidance systems include Global Positioning System (GPS) and Inertial Navigation Systems (INS).
