within the next couple of days. The station will be down for approximately 
3 months while the county garage is undergoing some major rehabilitation.

I have checked into the problem, and have it identified.  The laptop there 
has a fatal error and needs to be rebuilt. I am in this process but it looks 
like it will take 2 more weeks,  I will keep you advised.

the server.  As soon as things are operational again, I will 
update.  Unfortunately data files were not collected during this

Oklahoma CORS
Due to weather, power is out at various loctions across the State of Oklahoma.
The power companies say 7-10 days for complete recovery.   Add to this the 
forecast for more rain, sleet and freezing rain for the next few days, in short,
data download for ODOT CORS will be spotty at best.  I will be checking sites 
daily and will update you when they become reliable.  So for now, any data
received from ODOT CORS should be veiwed as the exception, not the rule.
Steve 'iceman' Telford 

North Carolina Geodetic Survey (NCGS) sites
We are experiencing difficulties downloading data from NCGS to Silver Spring.
However, we are able to download the data to our secondary server in Boulder.
From there we will pull the data and make it available here in Silver Spring so
OPUS and User Friendly CORS can have direct access to it.  This will be the
method until Monday Dec. 17, 2007

You can access our Boulder server directly at...
ftp://wwwest.ngs.noaa.gov/cors/rinex

AZGB - Globe, AZ
We will be doing some planned maintenance on the FTP and GPS servers on 17Dec07 during normal working hours.
The GPS server will have service packs installed coupled with server reboot resulting in loss of 1 hour of data.
The FTP server will be updated to a new version that may take a portion of the day.
Regards,
Tom Homan

Florida DOT CORS and UFCORS - Oct 12, 2007
Ongoing failures by UFCORS to provide data from sites from the FLDOT CORS
has been resolved. The issue revolved around compatability of user software
RINEX 2.10 and RINEX 2.11 and C2 observables. Previous data for the last 30
days will be corrected tonight, earlier data will require a delay of about
1 week. Sorry not to have been able to resolve this problem sooner. G. Sella.

Coop CORS members required to update station log files.

For many years the Cooperative CORS sites had little restrictions as to the style of their log files. We are now urging those members to follow the guidelines set forth by the International GPS Service ( IGS ). These guidelines were established in order to retrieve the necessary metadata easily and without error. For more information on creating the proper file see Appendix 2 of the CORS Guidelines.
