Document Type and Number:
Japanese Patent JP6455873
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a vibration measurement method, vibration detector, and vibration measurement program enabling accurate vibration measurement related to a displacement.SOLUTION: The vibration detector includes: one GNSS receiving unit 1 that is installed at a measurement point and receives a signal from a satellite; and an arithmetic processing unit 2 that acquires a reception signal output from the GNSS receiving unit at predetermined time intervals, acquires the reception signal from the GNSS receiving unit at two adjacent times, calculates the time difference of Doppler variation from the two reception signals, determines a displacement amount on the basis of the calculation result, and integrates the differential amount of the displacement amount to determine the vibration.SELECTED DRAWING: Figure 1
