Correction of Misalignment Errors in the Integrated GNSS and Accelerometer System for Structural Displacement Monitoring

Figure 12

(a) Differences between the displacements computed with the fusion of GPS-2 and ACC-2 data with MRKF and from GPS-2 data only and between the MRKF-derived displacements and those computed from the fusion of GPS-2, GPS-3, and ACC-2 data with UMRKF-MA, all for GPS-2 station. (b) Tilt angles of the bridge deck at GPS-2 station computed from MA-GPS observations and from estimation using the UMRKF-MA.
