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.
