Abstract: The present invention relates to a spatial coordinate positioning system, particularly to a spatial coordinate positioning system which is capable of measuring a position of spatial positioning target in high-precision by calculating spatial coordinates of assistant point stations at a predetermined interval on the basis of a coordinate of a ground base point station and distance information between the assistant point stations in a space where the plurality of assistant point stations are installed of which coordinates were unknown.
