Title:
SYSTEM AND METHOD FOR SYNCHRONIZING BEIDOU NAVIGATION-BASED DISTRIBUTED MAGNETOTELLURIC APPARATUSES
Document Type and Number:
WIPO Patent Application WO/2018/001360
Kind Code:
A1
Abstract:
A system (10) and method for synchronizing BeiDou navigation-based distributed magnetotelluric apparatuses. The method comprises: a transmitter (11) and a receiver (12) establish connections to a BeiDou satellite (13), respectively, and perform location positioning and timing synchronization (S1); the transmitter (11) and the receiver (12) acquire a pulse per second signal, and adjust, according to the pulse per second signal, temperature compensated crystal oscillation frequencies thereof to achieve preconfigured frequencies (S2); and in an outdoor operation, the transmitter (11) and the receiver (12) communicate with each other via the BeiDou satellite (13), and timely adjust an operation process (S3). According to the embodiment of the invention, the synchronization system and method can combine timing, positioning, communication functions into one, facilitating timely adjustment of a data acquisition process, thereby ensuring quality of data acquisition and increasing efficiency of an outdoor operation.
