Definition
The standard reference frame for the circular restricted three-body problem. The origin is at the common center of mass of the two primary bodies, the x-axis points from the larger to the smaller body, the z-axis aligns with the system's angular momentum, and the y-axis completes the right-handed system. In this rotating frame, the spacecraft equations of motion include Coriolis terms, and the five Lagrange points are stationary.
