High-rise Buildings GPS Data Processing Based on Wavelet Analysis

  Using GPS to hightime dynamic observation is considered to be effective, how to deal with massive amounts of GPS observation data vibration is an important issue. In order to improve the automation of process GPS data, based on GPS observation data vibration characteristics, wavelet analysis technology was applied to the GPS observation data processing in this paper. The impact of different wavelet decomposition scales and wavelet bases and threshold criterion to GPS observation data derise buildings, beneficial conclusions are obtained.
