On analysis of transformation parameters in real-time dynamic GPS measurement technique

Based on the fact that the solution of the transformation parameters is the foundation of the RTK measurement,the paper researches the identification of the coordinate transformation parameters,illustrates the influence of the selection for different control points on the residual errors by taking the calculation of the coordinating transformation parameters in some place of Ji'nan,and has the measurement and inspection,so as to meet the needs of the modern precise measurement requirements.
