🛰️Spacecraft Attitude Control

What do you learn in Spacecraft Attitude Determination and Control

You'll learn how to keep spacecraft pointed in the right direction and spinning at the correct rate. The course covers attitude kinematics and dynamics, control systems, sensors, and actuators used in space. You'll dive into topics like quaternions, Euler angles, reaction wheels, star trackers, and PID controllers. It's all about mastering the art of orienting satellites and other spacecraft.

Is Spacecraft Attitude Determination and Control hard?

It's definitely not a walk in the park. The math can get pretty intense, with lots of 3D rotations and control theory. But if you've got a solid foundation in dynamics and linear algebra, you'll manage. The concepts aren't too bad once you wrap your head around them, but be prepared for some brain-bending problem sets and simulations.
