Data Storage:
Data files are normally available online for at least 28 days, after which they will be deleted. Data are not archived prior to deletion and are therefore unrecoverable. Users are encouraged to download data as soon as possible.

File Naming (DAT files):
Each file is named using a MTSUDOYS.DAT format. MTSU is the station ID, DOY is the day of year, S is the hour of the day (A through X) based on GPS time (not local time). 

 

File Naming (RINEX files):

Files are named as described above for DAT files, except for the file extension: in place of "DAT" are standard RINEX file extensions.

 

To download data files:

 

Select the link "DAT, RINEX" above.  You will see a "File Download - security Warning" window pop up, asking you if you want to run the FTP batch file. Click Run and you will be taken to the login page for the base files FTP site. use the following login information to access the site:

username: gpsguest

password: guest

You are now logged in to the base files FTP site and can access files to download.

 

Click on either DAT or RINEX, depending on the type of file you wish to download. Navigate to the appropriate subfolder; subfolders are arranged by year/day of year/site (mtsu). All available files will be displayed. Right click the name of the desired file and select "Save target as..." to download the file to your computer. 


Important note: 

Unless the system is experiencing technical difficulties, the last file listed should contain data for the most recent complete GMT hour and the current date. Because your computer may cache and then display an earlier version of the window, it may not show the most recent files available. If the file you seek is more recent than the bottom file in the "ftp" window, the listing can be updated by refreshing the window.
