Median Orbit Repeatability (see table below): 9.0 cm
Beginning this week, we add three new candidate global stations. As with other
sites, these stations are 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)
GENO (Genova, Italy) 4507892.4757 707621.3856 4441603.4804
RIOP (Riobamba, Ecuador) 1255145.0273 -6253609.6002 -182569.8745
VENE (Venezia, Italy) 4379724.9130 957495.7955 4521605.1986
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: PIE1 (not USNO) used as reference clock days 003, 007, and 008.
WARNING: FAIR (not USNO) used as reference clock day 006.
WARNING: Data from ASC1, LPGS, NICO, SANT excluded day 003.
WARNING: Data from COCO, LPGS, NYAL excluded day 004.
WARNING: Data from COCO, HNPT, LPGS excluded day 005.
WARNING: Data from COCO, KOSG, NICO excluded day 006.
WARNING: Data from COCO, NICO excluded day 007.
WARNING: Data from NYAL excluded day 008.
WARNING: Data from NICO, NYAL excluded day 009.
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)
