Explore the intricacies of gravity gradient effects on spacecraft attitude in this comprehensive lecture. Delve into Euler rigid body equations with gravity gradient torque and analyze dynamics using Euler angles in small deviation approximation. Examine stability conditions for pitch, roll, and yaw, along with oscillation frequencies. Investigate the concept of torque equilibrium angle and its implications for spacecraft orientation. Study the gravity gradient stability chart and conditions for effective stabilization. Apply these principles to real-world scenarios, including the International Space Station. Gain valuable insights into space vehicle dynamics, attitude control, and the complex interplay of forces in the space environment.
