S# = session number, # = number of daily solutions
sig = standard deviation of weighted mean (unscaled)
wrms = weighted root mean square error (repeatability)
nrms = normalized rms (can be used to scale sig)
_____________________________________________________________________________
Remarks: (1) IGS and regional data are analyzed using two-tier (global and
regional distributed processing. The IGS data are divided into
two subnetworks, analyzed individually by GAMIT, and combined
in GLOBK to produce precise ephemerides. These are tightly
constrained in separate GAMIT solutions of the following
four regional subnetworks:
(1) California regional PGGA/BARD (ambiguities fixed)
(2) Los Angeles Basin DGGA (ambiguities fixed)
(3) North America CORS (ambiguities free)
(4) Western Europe (ambiguities free).
The weekly solution reported here is generated by GLOBK,
combining the six daily solutions (2 global and 4 regional)
for each day of the week (42 total solutions).
(2) The site coordinate repeatabilities reported in this newsletter
are the direct results of the GLOBK adjustment. We then apply
a filter to remove a common-mode position error from the
California sites. The filtered (and unfiltered) series are
available through the SOPAC Home Page (http://jon.ucsd.edu),
under SCIGN/SCIGN Map (click on site of interest).
(3) PGGA - Permanent GPS Geodetic Array (Southern California)
DGGA - Dense GPS Geodetic Array (Los Angeles Basin)
BARD - Bay Area Regional Deformation Array (Northern California)
CORS - Continuously Operating Reference Stations (United States)
