We continue to deweight data from PRN11/GPS08 and PRN22/GPS22 for all days;
orbit repeatabilites for these spacecraft remain at the 1 meter and 10 meter
levels respectively. Data from MCMU have been excluded for the entire week of
analysis in accordance with IGS Message No. 209.
This week's analysis includes the processing of data from two new global network
stations: BRMU (Bermuda Islands) and HOBA (Hobart, Tazmania). Keeping in line
with our usual practices, data from these stations were deweighted for week 690.
The following nominal coordinates were assumed, and the station locations were
estimated (unconstrained) each day:
BRMU: X = 2304706.9968 m, Y = 4874815.1945 m, Z = 3395188.5590 m
HOBA: X = -3950184.0430 m, Y = 2522364.5480 m, Z = -4311588.6140 m
WARNING: Data from PRN11/GPS08 have been deweighted for the entire GPSweek 690.
WARNING: Data from PRN22/GPS22 have been deweighted for the entire GPSweek 690.
WARNING: Data from MCMU have been excluded for the entire GPSweek 690.
