Data from this satellite did not meet our initial convergence criteria for these days, and were excluded from our analyses accordingly. Beginning this week, we include data from SPK1 (Saddle Peak CA, USA). As with most stations, this site 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 = -2535988.3673 m, Y = -4642438.3100 m, Z = 3552159.6580 m 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 KIT3, TAIW excluded on day 155. WARNING: Data from KIT3, SHAO excluded on day 156. WARNING: Data from LAMA, SHAO, TAIW excluded on day 157. WARNING: Data from PRN22 excluded on days 158 and 159 due to a maneuver. WARNING: Data from GUAM, KIT3, LAMA, SHAO, TAIW excluded on day 158. WARNING: Data from KIT3 excluded on day 159. WARNING: Data from GUAM, TAIW, WETT excluded on day 160. WARNING: Data from GUAM, TAIW excluded on day 161. In the following table, UT1R-UTC are the integrated values based on estimated LODR values in the adjacent column.
