AC
AC stands for Attitude Control. It refers to the ability of a spacecraft to control its orientation and maintain a desired attitude or pointing direction in space. Attitude control is crucial for the success of a mission as it enables the spacecraft to point its instruments towards the target, maintain communication with Earth, and control its thermal environment. Attitude control systems typically use thrusters, reaction wheels, and gyroscopes to adjust the spacecraft's orientation. The control algorithms are designed to take into account various factors such as the spacecraft's mass, shape, and center of gravity, as well as external disturbances such as solar wind and gravity gradients.
