attitude control

In spaceflight, attitude control refers to a spacecraft's ability to maintain its orientation and precisely point its instruments toward specific targets. This is crucial for various functions, including scientific observation and communication.1

Automatic pilots, also known as attitude-stabilization-and-control systems in spacecraft, manage this orientation. They counteract disturbances from factors like micrometeorites, solar radiation pressure, and gravitational irregularities. Unlike aircraft that use aerodynamic surfaces, spacecraft employ reaction control jets, electromagnets, or gyroscopes for attitude adjustments.2

Navigation systems, often based on inertial guidance, work in conjunction with attitude control. These systems measure changes in velocity and use thrusters to correct the spacecraft's trajectory. Star trackers and ground control also play roles in refining the spacecraft's position and orientation for long voyages.3
