ATTITUDE MEASURING APPARATUS OF HEAVY MACHINE

PURPOSE:To measure the inclination, the direction and the position of a heavy machine simply and with high accuracy. CONSTITUTION:GPS antennas 11 to 14 are installed in four corner parts on a heavy machine, and GPS radio waves from a GPS satellite are received by respective receivers 15 to 18 through the individual GPS antennas 11 to 14. Thereby, individual pieces of coordinate data on the WGS-84 system (a worlwide positioning system) in the four corner parts on the heavy machine are acquired, the individual pieces of coordinate data are taken into a processor module 19, they are converted into a three-dimensional orthogonal coordinate system in conformity with the Japanese positioning system, the position, the inclination and the direction of the heavy machine are then computed in real time on the basis of individual three-dimensional coordinates, and the attitude of the heavy machine is measured.
