Deformation Information Extraction of GPS Dynamic Monitoring in Mining Area
摘要
Abstract
In order to improve accuracy in differential dynamic positioning for long distances, the Principal Component Analysis(PCA)was used to extract the Common Mode Error(CME), the coordinates series precision was improved. For further analysis surface movement by multi-source effects, the Independent Component A-nalysis(ICA), a method to solve blind signal separation problem, was used to extract deformation information about each station. Both the simulation test and measured data analysis showed that accuracy of three coordinate components were improved 46.1%, 71.0% and 36.8% by PC A, and the extraction of deformation information was achieved based on ICA of joint approximate diagonalization of eigenmatrix(JADE)algorithm.关键词
