    Three Body Rotating Coordinate System Type
    lang:""
    The lunar coordinate systems are primarily used when operating in close proximity to the Moon. There are, however, a few additional coordinate systems that are also useful when analyzing (and depicting) trajectories in the vicinity of the Earth-Moon system. They are rotating coordinate systems associated with two different three-body systems: the Sun-Earth-spacecraft system and the Earth-Moon-spacecraft system. The Sun-Earth and Earth-Moon rotating coordinate frames are defined as follows. The pole vector or Z-axis of the coordinate frame is set equal to the instantaneous orbit normal of the secondary (smaller) body about the primary (larger) body and the X-axis is set equal to the vector from the primary body center of mass (CM) to the secondary body CM. The X-axis rotates at a rate equal to the instantaneous rotation rate of the secondary body about the primary body.
