METHOD AND DEVICE FOR MEASURING MOVING INFORMATION, AND COMPUTING SYSTEM FOR MOVING INFORMATION

摘要

PROBLEM TO BE SOLVED: To continuously conduct highly precise measurement with a millimeter unit of precision without using a special instrument, in a GPS surveying method. SOLUTION: This moving information measuring device for receiving a signal from an artificial satellite GPS to measure moving information of an observation point based on surveying information from the observation point comprises an antenna 2 for receiving the signal from the artificial satellite GPS, a positioning processor 12 for finding the first positioning data based on the signal received by the antenna 2, a positioning data storage part 33 for storing the positioning data found by the processor 12, an extraction part 32 for extracting the second positioning data corresponding to the observation cycle before the last cycle of the artificial satellite returning to the observation point with a prescribed cycle in the first positioning data, based on the positioning data stored in the storage part 33, and a moving information computing part 31 for conducting an comparison operation based on the first and second positioning data.
