PRODUCTS GENERATED:
The following products are generated and uploaded into CDDIS @ NASA/GSFC
   EMR11670-6.SP3     GPS ephem. files for days 0-6, week #1167 in sp3 format 
   EMR11677.ERP       pole x,y and DUT1 solutions for week #1167
   EMR11677.SNX       station and EOP weekly combined solution in SINEX format
   EMR11677.SUM       name of this text summary file

REMARKS on EMR products:
1. ALGO receiver clock used as reference time. In the sp3 EPH file sat. clock
   correction value of 999999.999999 microseconds indicates that the direct clock 
   comparison with the reference clock is not available (e.g. ALGO not observing
   a satellite). 
   ALGO clock error & drift were about 2175.1 ns (52413) & 26.5 ns/day w.r.t.
   GPS time
   NRC1 clock error & drift were about -95.8 ns (52417) & 10.1 ns/day w.r.t.
   GPS time
   YELL clock error & drift were about 557.4 ns (52418) & 18.9 ns/day w.r.t.

     (R)  Satellite was removed from EMR SP3 file.
     (E)  Satellite was excluded prior to processing data.
     (M)  Satellite in maneuver.

3. Beginning with Week 1167 day 0 (May 19, 2002) the EMR final solution is  
   estimated with fixed ambiguities.  Ambiguities fixing for the EMR rapid
   solutions was initiated on week 1167 day 3 (May 22, 2002).
