Median Orbit Repeatability (see table below): 10.0 cm
Beginning day 313, we use MAD2 as a fixed site instead of MADR. As this new
site utilizes a Turbo-Rogue receiver, we analyze all pseudorange from this
station; these data were excluded when the older, regular Rogue was used.
Since MAD2 operates with the same Deep Space Network GPS antenna as MADR, the
constrained nominal coordinates have not changed.
We have recently discovered an error in our treatment of the solar radiation
pressure estimate for PRN03 which has existed since its inclusion in our
processing beginning in April, 1996. The problem has been corrected beginning
with day 313 (GPS week 931, day 0).
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 HOLP, KELY, SANT, SELE, ZECK excluded day 314.
WARNING: Data from HOLP, POTS excluded day 315.
WARNING: Data from SNI1, THU1 excluded day 317.
WARNING: Data from KERG excluded day 319.
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)
