Mean Orbit Repeatability (see table below): 23.0 cm
(excluding PRN03 on all days).
According to IGS Mail Message No. 1278, the Rogue receiver at FAIR was replaced
with the TurboRogue receiver used at FAI2 on day 107. As FAIR is a fiducial
site, we have deliberately excluded data from the receiver at this monument on
this and the following day, 108.
Beginning this week, we add a new station to our global network. 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)
GALA (Galapagos Islands): -33770.2804 -6377516.2565 -82093.9876
Although the newly launched satellite PRN03 was used in all of our analyses
this week, there was some mismodeling as shown by our orbit repeatability
table. We have chosen to remove this satellite from our sp3 orbit products
for all days this week.
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 BRAN, FAIR, LPGS, MALI, MAS1, MATE, POTS, SFER, TABL, TIBB, UPAD, USC1 excluded day 105.
WARNING: Data from BOGT, BRAN, FAIR, KELY, LPGS, MATE, NYAL, POTS, SFER, TABL, TIBB, TRAK excluded day 106.
WARNING: Data from BRAN, FAI2, FAIR, KELY, LPGS, MAS1, MATE, NYAL, OHIG, POTS, SFER excluded day 107.
WARNING: Data from FAI2, FAIR, IISC, KELY, MAS1, MATE, MCM4, SFER, VNDP excluded day 108.
WARNING: Data from FAIR, GOPE, KELY, LAMA, MATE, SHAO excluded day 109.
WARNING: Data from MATE, POTS, SFER, TRAK excluded day 110.
WARNING: Data from BOGT, POTS, SFER, SHAO excluded day 111.
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)
