WebDec 2, 2024 · For example, in the term "LVLH", "vertical" is a vector, but "horizontal" is a plane. Therefore, any rotation of an LVLH system about its V axis has the same local horizontal, though the basis vectors chosen may differ widely. Also, when you're in space, what exactly does "vertical" mean? With respect to what? http://www.ee.nmt.edu/~elosery/spring_2016/ee570/lectures/coordinate_frame_transformations.pres.pdf
