PRODUCTS GENERATED:
The following products are generated and uploaded into CDDIS @ NASA/GSFC
   EMR09030-6.SP3     GPS ephem. files for days 0-6, week #0903 in sp3 format 
   EMR09037.ERP       pole x,y and DUT1 solutions for week #0903

REMARKS on EMR products:

	WARNING :  Due to incomplete data at ALGO, the following stations
		   were used as reference clock :
		
		   NRC1 on 97apr30 (50568) and 97may03 (50571)
		   FORT on 97may01 (50569)
		   FAIR on 97may02 (50570)

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). 

   ALGO clock error & drift were about 316 ns (50565) & 65 ns/day w.r.t. GPS
   time.
