A satellite in a direct orbit with an orbital period less than one day will tend to move from west to east along its ground track.
As the spacecraft moves along, this mirror sweeps the ground creating a scan swath that extends roughly 800 kilometers on either side of the ground track.

To maintain a fixed ground track it is also necessary to make out-of-plane manoeuvres to compensate for the inclination change caused by Sun / Moon gravitation.
