Mean Orbit Repeatability (see table below): 19.8 cm
Beginning this week, we have increased the number of stations regularly used
in our precise orbit computation from 34 to 37. Additionally, we exclude data
from PRN12 from our analyses beginning day 305.
According to IGSMail Message No. 1104, the GPS antenna at GOLD was replaced on
day 304. Because we analyze a 30-hour data interval, we have chosen not to use
GOLD as a fiducial (fixed) station on days 304 and 305.
Beginning this week, we include data from two new stations. As with most
stations, 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)
NOTO (Noto, Italy): 4934529.8301 1321262.3166 3806480.6209
USNA (Annapolis, MD): 1160669.4791 -4826885.7609 3990865.9356
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 BRAZ, IISC excluded day 302.
WARNING: Data from CMP9, DAV1, IISC, KELY, SEY1, UPAD excluded day 303.
WARNING: Data from CHIL, HOLP, SANT excluded day 304.
WARNING: Data from PRN12 excluded days 305-308.
WARNING: Data from CHIL, CRFP, DAV1, FARB, GOLD, HART excluded day 305.
WARNING: Data from CHIL, DAV1, FAIR, GOLD, HART, KELY, LAMA, NOTO, SIO3, TABL, WHI1 excluded day 306.
WARNING: Data from CHIL, CLAR, DAV1, GOLD, HART, HOLP, KELY, MATE, NOTO, SIO3, TABL excluded day 307.
WARNING: Data from CLAR, GOLD, HOLP, KELY, KOKB, MATE, SIO3, TABL excluded day 308.
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)
