A ground track refers to the path that an object (such as a satellite or an aircraft) traces on the Earth's surface as it moves through the atmosphere or space. Specifically, this term is often used in the context of satellites orbiting the Earth. When a satellite orbits the Earth, it continually moves over different points on the Earth's surface. The ground track is essentially the projection of the satellite's orbit onto the Earth, showing where the satellite is located at various points in its orbit over time.

Walter Kaufmann (1871–1947) was a notable physicist known for his work in the early 20th century, particularly in the field of electromagnetism and the theory of relativity.
