The description of the Station's flight attitude (orientation relative to the plane of its orbit) is referenced to local-vertical/local-horizontal (LVLH) axes that are fixed with respect to the Station's near-circular orbit (i.e., not to the physical Station). The LVLH origin is at the Station's center-of-mass; the z-axis points radially toward the Earth's center (or toward the nadir direction), the x-axis points along the orbital velocity vector (the ram direction, with wake being opposite), and the y-axis completes the right-handed triad. The flight attitude of the Station is then described using a second, Station-fixed, coordinate system whose orientation relative to LVLH is specified using the Eulerian angles of yaw, pitch and roll. Several Station-fixed coordination systems are defined. The most widely used is the Space Station Reference Coordinate System, ... in thich the positive x-axis points along the axis of the U.S. lab away from the Zarya and Service Modules; the positive y-axis points starboard along the main truss, and positive z completes a right-handed coordinate system.
