CORS Global Navigation Satellite System (GNSS - GPS) data for all sites are kept online since April 20, 1994 to present. Required station data and information files can be found by highlighting the desired elements below and then clicking on the Find Files button. We have developed a User Friendly CORS (UFCORS) to join days, get partial days, interpolate or decimate the data.
To see if there were any problems on your requested observing day, select Data Availability. You can also look at the short-term Time Series for problems.
|sort by state or country code - sort by city - sort by site ID|
Do not be confused by the times listed to the right of the next page. They are the times the files were posted. The 8th character in the file name indicates the data range: "a" 0:00 UT - 0:59 UT , "b" 1:00 UT - 1:59 UT, ..., "x" 23:00 UT - 23:59 UT. The files with 24 hours worth of data have a 0 (zero) in the 8th place.
