Correction of Misalignment Errors in the Integrated GNSS and Accelerometer System for Structural Displacement Monitoring
Figure 5
PSD results of displacements computed from the MA-GNSS, the accelerometer (ACC) measurements, the EMD-based fusion algorithm (EMD), the conventional Kalman filter (CMRKF), CMRKF-MA, and UMRKF-MA based on data from sinusoidal displacement simulation. The PSD results of the laser measurements are also given as the truth for comparison.
