******************************************************************************
Author: M B Heflin
Subject: Resubmit: Wk 0865 JPL GNAAC Analysis Report
An error was made for weeks 865 and 866 only which caused the file from GFZ to
be used twice, once as the solution for GFZ and once as the solution for SIO.
The following solution corrects the problem for week 866. New files have been
sent to the CDDIS.
******************************************************************************
GNAAC COMPARISON FROM JPL FOR GPS WEEK 865 AUG 04, 1996 - AUG 10, 1996
******************************************************************************
M B Heflin, J F Zumberge, D C Jefferson, M M Watkins, F H Webb
all at the Jet Propulsion Laboratory, California Institute of Technology,
Pasadena, CA 91109.
Solutions in SINEX format were obtained from COD, EMR, 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.
Remarks: A weekly solution from NGS was constructed by combining their daily
submissions.
