PRODUCTS GENERATED:
The following products are generated and uploaded into CDDIS @ NASA/GSFC
   EMR08990-6.SP3     GPS ephem. files for days 0-6, week #0899 in sp3 format 
   EMR08997.ERP       pole x,y and DUT1 solutions for week #0899
   EMR08997.SNX       station and EOP weekly combined solution in SINEX format
   EMR08997.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 52 nsec (50537) & 56 nsec/day w.r.t.
   GPS time.

3. KIT3 was excluded from the EMR solutions from March31 to Apr05 due to
   noisy data.

4. PAMA was removed from the sinex solutions of Apr02 and Apr05 due to
   relocation of the site.
