PRODUCTS GENERATED:
The following products are generated and uploaded into CDDIS @ NASA/GSFC
   EMR07530-6.SP3     GPS ephem. files for days 0-6, week #0753 in sp3 format 
   EMR07537.ERP       pole x,y and DUT1, LOD solutions for week #0753
   EMR07537.SUM       name of this text summary file

REMARKS on EMR's products:
1. ALGO hydrogen maser used as a time reference. In the sp3 EPH file sat.
   epochs with no reference (e.g. ALGO not observing a satellite) have a value 
   of 99999. microseconds. 
   ALGO clock error & drift were about -2330 ns (49515) & -34 ns/day w.r.t.
   GPS time. 
2. NRC1 used as a time reference for June 18 (day 169), estimated
   clock error and drift for NRC1 were about 292ns (49521) & -20ns/day.
   (ALGO data file not comlete on this day)
3. Starting with week 753 we also estimate UT1 rate (LOD) in addition to
   UT1-UTC to mitigate errors in apriori UT1-UTC rates.
4. Starting with week 753 we are using the new suggested ERP format
   which includes estimated LOD and apriori rates for pole x,y.
5. Modelling problems with PRN12 on June 16-18 (day 166-169), may be caused
   by eclipsing. The sv included in our sp3 orbit files with increased sigmas.
6. Problem with STJO data on June 12 (day 163), station deleted from our
   processing on this day.
