The instructors will lecture on the orbit and attitude control of a spacecraft, and structural dynamics.
In this course, students will learn about the basics of the following topics.
- Orbit of a spacecraft
Sphere of influence, the patched conic method, interplanetary/moon orbits, three-body problems
- Spacecraft attitude
Coordinate transformation, attitude representations, kinematics, dynamics, disturbance torque (gravity-gradient, solar radiation, electromagnetic and other torque), nutation of spin satellites, and various types of attitude control, such as control of gravity gradient stabilized satellites, stabilization control of spin satellites, control of three-axis stabilized satellites, attitude change control.
- Structural dynamics
Lords and dynamics for rocket structure, interaction between structural oscillations and aerodynamic loads, such as divergence and flutter, structural oscillations and sloshing, pogo effect, and flexible space structures, in particular, the basics of structural dynamics of membrane space structures
|✔ Applicable||How instructors' work experience benefits the course|

To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.
