Abstract
Vondrak bandpass filter, which has good signal resolution over its signal truncation frequency band and is effective in separating structural vibrations from global positioning system (GPS) multipath effects, was applied to GPS structural deformation monitoring. Real GPS observations were used to test the performance of the proposed filter. The results show that the method has the potential to improve the quality of GPS results, which can successfully extract the desired vibration signals from the point coordinate series and separate the structural vibrations and multipath signals from the double-difference carrier-phase observation residuals series.
