Median Orbit Repeatability (see table below): 10.0 cm
Although used in each day's analysis, we continue to deweight data from PRN13.
This satellite does not appear in any of the orbit products for this week.
Beginning this week we add two new candidate stations, SELE and SOFI. As with
other sites, these stations 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)
HNPT (Cambridge MD, USA) 1196626.4857 -4846358.5654 3956723.1234
PIN2 (Pinyon Flats2 CA, USA) -2369466.5035 -4761231.7315 3511396.7120
ROCH (Pinemeadow CA, USA) -2382183.3937 -4755085.3075 3511367.8757
WSRT (Westerbork, The Netherlands) 3828736.2583 443304.8819 5064884.9859
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: FAIR (not ALGO) used as reference clock days 243 and 244.
WARNING: Data from PRN13 deweighted the entire GPS week 921.
WARNING: Data from CAGL, CAT1, TAIW excluded day 243.
WARNING: Data from CAGL, TAIW excluded day 244.
WARNING: Data from CAGL, TAIW, TIDB excluded day 245.
WARNING: Data from DGAR, TRAK excluded day 246.
WARNING: Data from KOUR, PIN1, SIO3 excluded day 247.
WARNING: Data from CSN1, SIO3 excluded day 248.
WARNING: Data from CRO1, CSN1, SIO3, SNI1 excluded day 249.
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)
