Subject : [IGSSTATION-5104] low data yields at BAKE, DUBR, GLDR, IRKT, ISCO, (30971)
FROM . Jim Ray - jimr@NGS.NOAA.GOV
Date : 25-Sep-2012 20:12 -
To : igsstation@igscb.jpl.nasa.gov
Stations : BAKE, DUBR, GLDR, IRKT, ISCO
Author: Jim Ray

It is great to see the list of stations with data yields <80% (from the CDDIS
status file for doy 260) is getting shorter. Most of the 19 stations on this
list were among the 29 stations listed last time, but a few new names have
joined. Hardware problems might explain some, but many probably still are not
recording L2 P-code data from GPS Block IIR-M and IIF satellites due a
receiver setting or translation issue.
