PRODUCTS GENERATED:
The following products are generated and uploaded into CDDIS @ NASA/GSFC
   EMR9020-6.SP3     GPS ephem. files for days 0-6, week #902 in sp3 format 
   EMR9027.ERP       pole x,y and DUT1 solutions for week #902
   EMR9027.SNX       station and EOP weekly combined solution in SINEX format
   EMR9027.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 99999.999999 microseconds indicates that the direct clock 
   comparison with the reference clock is not available (e.g. ALGO not observing
   a satellite). 

2. ALGO clock error & drift were about 795 nsec (50558) & 65 nsec/day 
   w.r.t. GPS time. 

   DRAO clock error & drift were about 2211 nsec (50560) & 70 nsec/day 
   w.r.t. GPS time.

   NRC1 clock error & drift were about 83 nsec (50561) & 5 nsec/day 
   w.r.t. GPS time.
