Mean Orbit Repeatability (see table below): 18.9 cm
Beginning this week, we include data from a new site, TABL (Table Mountain
Observatory, CA USA). As with most stations, this site is given the
opportunity to participate in the orbit and clock solution as the global site
distribution varies. The following nominal coordinates were assumed:
X (m) Y (m) Z (m)
-968332.9300 3794424.1200 5018164.8100
As mentioned in some of our previous IGS reports, we have been excluding
pseudorange data from several sites based on atypically high postfit residuals
from these stations. In keeping with this practice, we now exclude P-code
data from LONG (Longdon yard, CA USA) and the aforementioned new site TABL.
Simultaneously, this week we also reinstate P-code from the following ground
sites which have had an apparent improvement in receiver performance: BOGT,
CASA, LAMA, MCM4, and RCM5.
Due to potential problems, data from stations mentioned below were not
considered for use in the global solution for the day indicated. (For
geographical reasons, they may not have been used in any case.)
WARNING: Data from DAV1, KELY, MAS1 excluded day 295.
WARNING: Data from DAV1, FAIR, LAMA, SEY1 excluded day 296.
WARNING: NLIB (not ALGO) used as reference clock on day 296.
WARNING: PIE1 (not ALGO) used as reference clock on days 297 and 298.
WARNING: Data from IISC, LAMA excluded day 297.
WARNING: Data from AREQ, IISC, LAMA, MCM4 excluded day 298.
WARNING: Data from AREQ, BRAZ, IISC, LAMA, MCM4, MOIN excluded day 299.
WARNING: Data from AREQ, IISC, MCM4 excluded day 300.
WARNING: Data from HOLC, IISC, KELY excluded day 301.
In the following table, UT1R-UTC are the integrated values based on estimated
LODR values in the adjacent column. See IGS Report No. 1498 (jpl07827.sum)
