We continue to use our normal processing strategies under these conditions. According to the file nanu1995.mes obtained from the IGS CBIS, PRN16 was unusable on days 107 and 108 (Apr 17, 18) due to maintenance/repositioning. Data from this satellite were excluded from these days' processing. Similarly, PRN26 was unusable on day 109 (Apr 19). Data from this satellite did not meet our convergence criteria on this nor the following day (110), and were excluded from our processing accordingly. Beginning this week, we begin to include data from MDVO (Mendeleevo, Russia). 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 = 2844653.1259 m, Y = 2161065.7727 m, Z = 5266371.6028 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 CASA excluded for all of GPS week 797. WARNING: Data from MATE excluded on day 106 (Apr 16). WARNING: Data from PRN16 excluded on days 107 and 108 (Apr 17, 18) due to a maneuver. WARNING: Data from ZWEN excluded on day 108 (Apr 18). WARNING: Data from PRN26 excluded on days 109 and 110 (Apr 19, 20). WARNING: Data from WETT excluded on day 109 (Apr 19). WARNING: Data from POTS, WETT excluded on day 110 (Apr 20). In the following table, UT1R-UTC are the integrated values based on estimated LODR values in the adjacent column.
