Median Orbit Repeatability (see table below): 6.0 cm
A clock discontinuity (reset) of about 3 microseconds was detected for
PRN07 at approximately 05:35 on day 327.
This week, we add four new candidate global stations. As with other sites,
these sites 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)
CAGS (Gatineau, Quebec, Canada) 1096349.1359 -4335060.7252 4533255.2783
HOLM (Holman, NWT, Canada) -983071.9378 -1867623.6954 5998639.6874
INVK (Inuvik, NWT, Canada) -1628432.1031 -1714393.1007 5903844.8792
RESO (Resolute, Nunavut, Canada) -144107.5251 -1683119.8140 6129763.3931
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 PRN17 exclued the entire GPS week 1141.
WARNING: Data from PRN37 excluded day 328.
WARNING: Data from AREQ, AZU1, BILI, BJFS, CAGS, CORD, DUBR, LBCH, MANA, OHIG, RIOG, SOL1, SSIA, SUTH, TABL, TEGU, TORP, VNDP, WHC1, WTZA excluded day 322.
WARNING: Data from AREQ, CAGS, CORD, DUBR, KELY, LBCH, MANA, OHIG, RIOG, RIOP, SOL1, SSIA, SUTH, TEGU, TORP, WTZA excluded day 323.
WARNING: Data from AREQ, CORD, DUBR, FORT, MANA, OHIG, RIOG, RIOP, SOL1, SPK1, SSIA, SUTH, TEGU, WTZA excluded day 324.
WARNING: Data from DRAG, DUBR, HILO, HOLC, KERG, SPK1, UPAD, WTZA, ZWEN excluded day 325.
WARNING: Data from BOR1, GLSV, HILO, KERG, RABT, RIOP, WTZA excluded day 326.
