網頁The Z -axis is determined by the right-hand Cartesian coordinate system, which is vertical to the illuminated scene plane and points to the Earth center inversely. It can be used to express the orbit height of the LEO satellite. The coordinate origin O is the starting nadir point of the LEO satellite. Figure 1.
