Starting with this week 1069, we submit products that are aligned with the chosen terrestrial reference frame via 3 translations in addition to the 3 rotations already performed. The scale transformation remains undone, and free-network clock and tropospheric estimates are still reported directly with no transformation. GENERAL ------- This week, we add a new candidate global station. As with other sites, 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 (m) Y (m) Z (m) DRAG (Metzoki Dragot, Israel) 4432980.8009 3149432.0999 3322110.3424 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: ALGO (not USNO) used as reference clock the entire GPS week 1069. WARNING: Data from PRN02 excluded days 184-188. WARNING: Data from PRN18 excluded the entire GPS week 1069. WARNING: Data from AMMN, CHIL, ESTI, KOUR, WTZT excluded day 184. WARNING: Data from BARB, JAMA, KOUR, KUNM, TORP, WTZT excluded day 185.
