Changes in the process and format will be forthcoming to prevent delay of the Analysis Center(AC) comparison when data is absent. R F Meyer (Raytheon, Pasadena, CA); M B Heflin, J F Zumberge, D C Jefferson, M M Watkins, F H Webb (Jet Propulsion Laboratory, California Institute of Technology, Pasadena, CA) Solutions in SINEX format were obtained from COD, EMR, ESA, GFZ, JPL, NGS, and SIO. Each center was compared to each other center by estimating a 7-parameter Helmert transformation to minimize the least-squares coordinate residuals. The following table summarizes comparison results. The North, East, and Vertical WRMS values are given in mm for each pair. The number of common sites is given directly underneath the values for WRMS. The number underneath each center's name is the scale factor applied to the formal errors from that center. Transformation parameters for each pair are given at the end of the report. We also compute a free-network combination of solutions from all centers. Each solution is scaled and edited according to the results of pairwise comparisons. Then all free-network solutions are rigorously combined using their full covariance matrices. Sites common to all solutions are used to compare individual solutions with the combination and residuals are given in the first row of the comparison table.
