Bridge and Road Safety

Adopt Kalman filtering and Hilbert-Huang transform for data preprocessing, and
accurately calculate Beidou/GNSS surface displacement data. Mechanical models
are applied to control data quality of bridge vibration and deflection parameters.
Heterogeneous data fusion provides accurate and efficient data support for machine
learning-based bridge accident risk assessment models.
We also provide Beidou ground-based augmentation services with stable satellite
signal reception.
