GPS Network report
Note: The following section shows
the report generated by the least squares adjustment of the GPS
network. Explanations of the report are included in the
report section and are in bold text.

3-DIMENSIONAL ADJUSTMENT REPORT
===============================
The following section shows the
unadjusted measurements that make up the network. The control
coordinates are displayed first followed by the GPS vectors. The
control coordinates are displayed as latitude/longitude, SPC Grid
XYZ, and geocentric XYZ. If geoid modeling is set both ellipsoid
and orthometric elevations are displayed, ellipsoid elevation in
the latitude/longitude section and orthometric elevation in the SPC
section. The GPS vector section shows the unadjusted delta XYZ,
variances and covariances of the vectors.
