PRODUCTS GENERATED:
The following products are generated and uploaded into CDDIS @ NASA/GSFC
   EMR10710-6.SP3     GPS ephem. files for days 0-6, week #1071 in sp3 format 
   EMR10717.ERP       pole x,y and DUT1 solutions for week #1071
   EMR10717.SNX       station and EOP weekly combined solution in SINEX format
   EMR10717.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 236 ns (51742) & 15 ns/day w.r.t.
   GPS time. 

2.      Date  |  PRN  | Action |     Period     |      Reason
     +--------+-------+--------+----------------+----------------------------+
      00jul17 |   15  |    R   | 20:00 to 23:45 | Modeling Problems
