The guidance, navigation, and control (GNC) system is a critical component of a spacecraft that enables it to accurately maneuver, control its orientation, and navigate through space. The GNC system is responsible for ensuring that the spacecraft reaches its intended destination, maintains its desired trajectory, and performs the necessary maneuvers to achieve mission objectives. It comprises several key components, each playing a specific role in the overall functionality of the system.
1. Guidance System: The guidance system determines the spacecraft's desired trajectory and provides instructions for the control system to achieve it. It takes into account factors such as mission requirements, target destination, and environmental conditions to compute the optimal path and generate commands for the control system.
2. Navigation System: The navigation system enables the spacecraft to determine its position, velocity, and orientation accurately. It utilizes various sensors and instruments, such as star trackers, inertial measurement units (IMUs), and GPS receiv....
