Attitude control system

In spaceflight, the attitude control system (ACS) or attitude determination and control (ADAC) system of a spacecraft consists of equipment to measure, report and change the orientation of the vehicle.

Components

Some components of the attitude control system include:

* Astrionics
* Momentum wheels
* Reaction wheels
* Reaction control systems
* etc.

Dynamics

The ACS causes torques which spin the spacecraft. With an accurate model of the dynamics of the spacecraft, those torques can be used to control the spacecraft's attitude.
