PROBLEM TO BE SOLVED: To determine soundness of a structure to be measured by utilizing GPS. SOLUTION: This structure soundness determination system 10 is equipped with GPS antennas 12A-12D and a GPS receiver 13 installed on the roof of a building, and a computer 14 for calculating baseline vectors 15A-15E between the GPS antennas 12A-12D, based on observation data received from a GPS satellite by the GPS receiver 13. The computer 14 measures residual deformation of the building, by using the point of difference of a comparison element, between a reference triangle defined by the baseline vectors 15A-15E and actually measured triangle.
