Median Orbit Repeatability (see table below): 10.0 cm
We continue to exclude data from IGS stations that do not employ Dorne-Margolin
style antennae (see IGS Report #6260).
This week, we add two new candidate global stations. As with other sites,
these sites 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)
INEG (Aguascalientes, Mexico) -1260435.6702 -5788547.5545 2360340.1885
UNSA (Salta, Argentina) 2412830.4591 -5271936.7829 -2652209.1625
A large clock discontinuity (reset) of about 696 microseconds was detected
for PRN08 at approximately 09:55 on day 137. Also, the drift of the clock
onboard PRN16 experienced a shift from about +62 ps/s to -49 ps/s on day 136.
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: DRAO (not USNO) used as reference clock day 135.
WARNING: NRC1 (not USNO) used as reference clock days 136, 137, and 139-141.
WARNING: Data from PRN15 and PRN18 excluded the entire GPS week 1062.
WARNING: Data from PRN03 excluded day 135.
WARNING: Data from PRN03, PRN04 excluded day 136.
WARNING: Data from PRN02 excluded day 138.
WARNING: Data from PRN02, PRN07, PRN10, PRN21, PRN26 excluded day 139.
WARNING: Data from PRN02, PRN06, PRN21, PRN26, PRN29 excluded day 140.
WARNING: Data from PRN02, PRN17, PRn23, PRN26 excluded day 141.
WARNING: Data from GOL2, MAD2, NOUM, TID2, WTZT excluded day 135.
WARNING: Data from GOL2, MAD2, NOUM, TID2, TORP, WTZT excluded day 136.
WARNING: Data from GOL2, MAD2, TID2, TORP, UNSA, WTZT excluded day 137.
WARNING: Data from GOL2, MAD2, NYAL, QUIN, TID2, TORP, WTZT excluded day 138.
WARNING: Data from CIT1, GOL2, MAD2, TID2, TIXI, USC1, WTZT excluded day 139.
WARNING: Data from BILL, CIT1, CORD, DARW, GOL2, KELY, MAD2, QUIN, SOL1, TID2, USC1, USNO, WTZT excluded day 140.
WARNING: Data from BILL, DARW, GOL2, MAD2, TID2, WTZT excluded day 141.
