Median Orbit Repeatability (see table below): 18.0 cm
Since GPS week 878, we have been heavily deweighting data from PRN10 and
PRN30. Beginning this week, we weight data from both satellites normally.
Data from PRN10 appears to still be mismodeled, particularly on day 311,
and we have chosen to exclude its solution from this day's orbit product
(jpl08783.sp3).
According to the file nanu1996.mes obtained from the IGS CBIS, PRN28 is
unusable for an indefinite period beginning day 309. Data from this satellite
were used only in the analyses of this and the previous day, 308.
Beginning this week, we add three new candidate stations. As with most sites,
these 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)
DUBO (Lac du Bonnet, Canada) -417603.4463 -4064529.8923 4881432.3754
OBER (Oberpfaffenhofen, Germany) 4186556.3037 835029.2732 4723762.6366
RCM6 (Richmond FL, USA) 961334.7807 -5674074.1839 2740535.1463
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 FORT, WETT excluded day 308.
WARNING: Data from FORT, MEDI, WINT, YAR1, ZWEN excluded day 309.
WARNING: Data from SANT excluded day 310.
WARNING: Data from NYAL, SANT excluded day 311.
WARNING: Data from TROM excluded day 312.
WARNING: Data from ASC1, MADR, MAS1 excluded day 313.
WARNING: Data from TROM excluded day 314.
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)
