Spacecraft Dynamics and Attitude Control Systems

Understanding how satellites orient themselves in the harsh environment of space is critical to the success of any space mission. This text-based course guides you through the foundational physics and engineering principles behind spacecraft dynamics and attitude control. You will transition from understanding basic orbital mechanics to designing and analyzing practical attitude determination and control systems (ADCS). You will learn how spacecraft sense their orientation, process sensor data, and actuate control systems to maintain precise pointing. What you'll learn: - Understand the fundamental physics of rotational dynamics and coordinate transformations in space. - Analyze spacecraft sensors and actuators, including star trackers, gyroscopes, reaction wheels, and thrusters. - Apply modern attitude determination algorithms, including basic Kalman filtering concepts for sensor fusion. - Design feedback control loops to stabilize and point a satellite under external disturbances. - Evaluate spacecraft performance using modern simulation and modeling methodologies. The course starts with essential terminology, coordinate frames, and rotational kinematics before moving into dynamic equations, sensor-actuator modeling, and control system design. Every concept is reinforced with clear mathematical derivations, code-based logic representations, and step-by-step analytical exercises. This course is designed for aspiring aerospace engineers, students, and tech enthusiasts looking for a structured, beginner-friendly introduction to spacecraft guidance, navigation, and control.
