Our innovative elliptical compass (an instrument for drawing planetary orbits) enables the user to draw an ellipse without requiring any special tools, such as expensive computers and special-purpose software, or knowledge of how to use them. The elliptical compass draws an ellipse, by using two dimensions: the radius of the circle that forms the basis and the difference between the length of the major axis and the length of the minor axis of the ellipse.
