Step S112: and copying the intermediate frequency signal to obtain a carrier wave and a pseudo-range signal.
Specifically, the baseband signal processing module in the positioning module copies the local carrier and the pseudo-range signal consistent with the received GNSS signal according to the received digital intermediate frequency signal RF, and inputs the local carrier and the pseudo-range signal to the acquisition acceleration module.
Step S113: and obtaining the equal measurement values and navigation messages of the carrier wave and the pseudo-range signal according to the carrier wave and the pseudo-range signal.
Specifically, the acquisition acceleration module further realizes acquisition and tracking of the BDS/GPS/GLONASS/Galileo satellite, and obtains equal measurement values of pseudo range and carrier phase and demodulated navigation messages.
Step S114: and obtaining coordinate position data according to the carrier wave, the pseudo-range signal, the equal measurement value and the navigation message.
Specifically, the pseudorange and carrier signals output by the baseband signal processing module, the Doppler observation value acquired by the capturing acceleration module, the navigation message and other information are all sent to a first processor in the positioning module, and the first processor processes the information through a high-precision positioning algorithm embedded in the processor to obtain real-time centimeter-level high-precision coordinate position data of the tower where the monitoring device is located.
In one embodiment, step S120 is implemented based on a data operation module in the monitoring device, and includes:
step S121: and processing the coordinate position data obtained according to the period to obtain deformation data.
