Abstract:
Through transforming the particular solution of initial coordinates to the general solution of arbitrary coordinate, rank defect free net adjustment is analyzed, and the essence of the datum transformation is discussed. The results show that the optimized solution of rank defect free net adjustment is the one solution under the datum which is calculated by the approximation value. In practice, the key problem is to determine the appropriate datum. GPS monitoring network in Xi'an is taken as an example to demonstrate the different optimal solutions under different data, whereas the solutions in plate motion are physically significant.
