Announcement! After a long delay, Radford University again has a working Trimble base station (December 2005). Please feel free to use this data and to contact us with comments or suggestions!

Satellite GPS differential error correction data is collected by the GPS base station run by the department of geography at Radford University.  Files are collected once an hour 24 hours a day, seven days a week, and are posted on this web site hourly. Files will be kept for 30 days. Click on the file you wish to download, and it will be sent over the web to your computer.

File naming convention: There is one error correction file generated each hour. The file naming convention is as follows: site letter - last digit of year - month - day - hour  in UTC time (also known as "Zulu Time" or "Greenwich Mean Time").

Example:        05093010.DAT    

                                              05093010.DAT    means 2005

                                                       05093010.DAT    means the month (September)

                                                        05093010.DAT     means the day (30th day of the month)

                                                        05093010.DAT     means the hour file written (Local time)
