Deformation Measurement Based on the Phase of Reflected Signals of Beidou GEO Satellitesesearchers have begun to work on the phase applications of GNSS reflected signals for deformation measurement. Compared with the pseudorange measurement, the phase measurement can obtain the precision of less than one wavelength, and the phase is more sensitive to the motion of the target. This stud

Multi-path Error Correction Method for Slope Monitoring Based on BP Neural Network Fourier transform and BP neural network is proposed to solve the problem of periodic fluctuation of monitoring results. Firstly, Fourier transform is used to analyze the spectrum of monitoring results and extract the period and frequency of periodic signals. Then BP neural network is used to model

Simulation Research on ICAO Model Parameters Based on BDSabnormal fault models and parameters to join ICAO. The article establishes an equivalent ICAO model with BDS. According to the actual faults that may occur during the navigation signal generation process, the methods are respectively proposed to simulate the digital circuit failure (TMA) caused by t
