Zusammenfassung:	The invention relates to the technical field of satellite navigation enhancement, in particular to an engineering structure dynamic displacement monitoring device based on combination of a GNSS (Global Navigation Satellite System) and a gyroscope, which comprises a data acquisition module for inputting signals based on the GNSS and the gyroscope, receiving structure displacement and angular velocity, arranging GNSS data according to a time sequence, carrying out time label matching on the GNSS data and gyroscope data, and sending the GNSS data to the gyroscope; and executing time synchronization to obtain an original synchronous data set. According to the invention, through integration of input signals of the GNSS and the gyroscope, accurate time synchronization of displacement and angular velocity data is realized, consistency of data processing is improved, accurate reflection of a data set to dynamic change of a structure is enhanced through time label matching and synchronization, furthermore, resolution
