PRODUCTS GENERATED:
The following products are generated and uploaded into CDDIS @ NASA/GSFC
EMR09150-6.SP3 GPS ephem. files for days 0-6, week #0915 in sp3 format
EMR09157.ERP pole x,y and DUT1 solutions for week #0915
EMR09157.SNX station and EOP weekly combined solution in SINEX format
EMR09157.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).
ALGO clock error & drift were about 1727 ns (50649) & 81 ns/day w.r.t.
GPS time.
NRC1 clock error & drift were about 329 ns (50653) & 13 ns/day w.r.t.
GPS time.
