Algorithm and Application of Foundation Displacement Monitoring of Railway Cable Bridges Based on Satellite Observation Data

In order to realize real time monitoring of foundation displacement railway cable bridge based on satellite observation system, reasonable data sources and analysis duration are necessary, the influence various errors should be eliminated in process signal acquisition. this paper, validity settlement tower by is verified through accuracy stability tests. For eliminating multipath error random noise GNSS signal, a new method presented combining stationary wavelet transform empirical mode decomposition study. improving combing measured data, corrected establishing non-linear mapping between precise leveling BP neural network. Based that, tower.
