What are damper booms, and how do they facilitate triaxial stabilization?
I'd never heard of DODGE until I saw it mentioned this answer as the source of the first full color "full Earth" image. The spacecraft's primary function however was to experiment with gravity gradient stabilization for high orbits near…

PID Control with Error Rotation Matrices?
I'm modeling a rocket with PID controllers for thrust vectoring.
The PID controllers take in attitude errors as input, then output engine gimbal actuator commands.
The attitude errors are individual roll, pitch, and yaw angles that I obtain from…
