October 11, 2013 - Limited CORS Data Available for Areas in Colorado Impacted by Flooding
September 19, 2013 - NGS CORS Online Storage Transition From GPS Only to GNSS
The NGS CORS Team is ready to transition from GPS-only to GNSS online
storage of CORS data. (This includes only GPS+GLONASS data at the
present time.) The transition is scheduled for 1 October 2013. No
change in RINEX format will occur, because CORS data in our online
storage available via ftp or "Standard Download" have been in RINEX 2.11
format since 2007-Sep-10.
This transition will involve a number of steps:
2013-Aug-19: Updated CORS map to show which stations supply
GPS versus GNSS data (~800 out of ~1950).
2013-Aug-19: Until the transition date, GNSS RINEX data are available at:
yyyy-4 digit year, ddd-3 digit day-of-year, ssss-4 alphanumeric site id
GPS-only data remain available, as usual, at:
2013-Aug-19: UFCORS (User Friendly CORS) has a new beta version 4.0
that supports GNSS.
This beta version will remain available until the transition date, at
which point UFCORS3x will be terminated and replaced by UFCORS4.0. For
Pathfinder users this transition should be seamless. The biggest change
is that UFCORS3x provided GPS data that excluded L2C and L5 data, and
now will include GPS L2C, L5 and GLONASS, if available. Users will be
able to exclude GLONASS data but not specific GPS signals.
For questions about UFCORS please email ngs.ufcors @ noaa.gov
2013-Oct-01: Start distributing GNSS data to
We have data from selected sites all the way back to 2007 that will
replace previous GPS-only data files. The replacement of the older data
will take a few weeks to complete.
OPUS will remain unchanged using only GPS L1 and L2 data. If additional signals are included in the submitted file these will be removed before processing by NGS.
