Attitude

In space and astronautical engineering, attitude refers to the orientation of a spacecraft or satellite with respect to a reference frame. Attitude can be described by three angles, known as Euler angles, which define the spacecraft's orientation relative to a fixed coordinate system. Attitude control is the process of adjusting the spacecraft's orientation to achieve a desired attitude. This is typically done using thrusters or reaction wheels. Attitude determination is the process of measuring the spacecraft's attitude using sensors such as star trackers, sun sensors, and gyroscopes. Accurate attitude determination and control are critical for many space missions, including Earth observation, remote sensing, and satellite communication.
