all at the Jet Propulsion Laboratory, California Institute of Technology,
Pasadena, CA 91109.
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.
