Median Orbit Repeatability (see table below): 7.0 cm
A large clock discontinuity (reset) of about 802 microseconds was detected
for PRN08 at approximately 15:30 on day 075.
This week, we add a new candidate global station. As with other sites,
this sites 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)
YAKT (Yakutsk, Russian Federation) -1914998.9115 2308241.5787 5610225.6866
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 PRN15 and PRN18 excluded the entire GPS week 1105.
WARNING: Data from PRN17 excluded day 070.
WARNING: Data from EISL, NRIL, PIMO, SANT excluded day 070.
WARNING: Data from ASC1, NLIB, REYK excluded day 071.
WARNING: Data from ASC1, DAV1, KELY, MAG0, NICO, WEST, WTZT excluded day 072.
WARNING: Data from ASC1, CIT1, KSTU, SFER, WEST, WTZT excluded day 073.
WARNING: Data from ASC1, DGAR, NOUM, SANT, SFER, TEGU excluded day 074.
WARNING: Data from PETP, SFER, TEGU excluded day 075.
WARNING: Data from ESTI, TEGU excluded day 076.
