Title: | Combination of high- and low-rate GPS receivers for monitoring wind-induced response of tall buildings | Authors: | Yi, ZH Kuang, CL Wang, YR Yu, WK Cai, CS Dai, WJ |
Issue Date: | 2018 | Source: | Sensors, Dec. 2018, v. 18, no. 12, 4100, p. 1-15 | Abstract: | High-rise buildings are susceptible to wind-induced displacements, which can be precisely monitored by using GPS technology. However, GPS monitoring applications may be subject to signal interference and high hardware costs. This study presents a new wind-induced vibration monitoring approach that is based on the mixed use of high-rate and low-rate GPS receivers. In the proposed approach, high-rate receivers are only required in the monitoring stations, where we apply time-differenced positioning to obtain position changes between adjacent epochs. The derived high-rate monitoring station position changes are then integrated with low-rate single epoch relative positioning results between the monitoring and reference stations. Experimental results with both simulated and real data show that the proposed method has a comparable performance with the traditional relative positioning approach, in terms of determining buildings' vibration frequency, displacement, and acceleration. | Keywords: | High-rate GPS Wind-induced vibrations Time-differenced positioning Single-epoch relative positioning Precise point positioning |
