the lunar lander and the support bracket were not visible. Therefore, before assembly
the coordinate system of the lunar lander by the 3 pin holes should be transferred
to a visible coordinate system of optical cubic prism. I.e., the lunar lander coordinate system was replaced by a reference cubic prism coordinate system O j -M 1 K 1 N 1 .
