Median Orbit Repeatability (see table below): 16.0 cm
We no longer routinely exclude data from the following equatorial sites:
AREQ ASC1 BARB BOGT BRAZ COCO CRO1 DGAR FORT GALA GUAM IISC
KOKB KOUR KWJ1 MALI MKEA MOIN NOUM NTUS RIOP SEY1 THTI
However, the following days were processed before reverting to the nominal
strategy and did not use the sites listed above: 073, 075, and 077.
According to the file nanu1999.mes obtained from the IGS CBIS, PRN24 was
unusuable on day 075. Data from this satellite did not meet our initial
orbit convergence criteria on this day, and were mismodeled on the following
day (076) as well. We have excluded this satellite from the analyses of
both days. Additionally, data from PRN07 were mismodeled on days 076-078
and have been excluded from these days' analyses accordingly.
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 days 073-076 and 078.
WARNING: Data from PRN18 excluded the entire GPS week 1001.
WARNING: Data from ASC1, COCO, GOLD, KELY, KIT3, LPGS, URUM excluded day 073.
WARNING: Data from COCO, GOLD, KIT3, LPGS, MADR, NYAL, QUIN, SUWN, TAEJ, URUM excluded day 074.
WARNING: Data from PRN24, GOLD, LPGS, MADR, NOUM excluded day 075.
WARNING: Data from PRN24, PRN07, AMC2, DGAR, GOLD, LPGS, MAG0, MDVO, SANT, SEY1 excluded day 076.
WARNING: Data from PRN07, DGAR, GOLD, LPGS excluded day 077.
WARNING: Data from PRN07, ASC1, GOLD, HERS, KIT3, LPGS, MKEA, NICO, OHIG, URUM excluded day 078.
WARNING: Data from KIT3, LPGS, SANT, URUM excluded day 079.
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)
