TYPE TWO ANALYSIS CENTER COMPARISON FROM JPL FOR GPS WEEK 827 NOV 12 - 18 1995
******************************************************************************
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.
Remarks: A weekly solution from NGS was contstructed by combining five of
their daily submissions.
