High-rate RTK and PPP multi-GNSS positioning for small-scale dynamic displacements monitoring (original) (raw)

AI-generated Abstract

The study investigates the application of high-rate multi-GNSS positioning techniques, specifically precise relative GNSS and Precise Point Positioning (PPP), for monitoring small-scale dynamic displacements in engineering structures. Utilizing 20 Hz geodetic receivers, the research demonstrates the potential to detect displacements at the centimeter level in real-time applications. Results indicate that both techniques can effectively measure dynamic displacements to within a few millimeters, emphasizing the significance of signal processing methodologies.
