DME Data Distribution Site Restoration Update (Formerly https://ftp.agi.com)

*** UPDATED 4/1/2026 ***

On November 4, 2025, the system used to distribute STK databases and related data (including EOP, space weather, GPS almanac, leap second, and satellite TLEs) was taken offline while our team made updates to improve the service experience. As of March 31st, 2026, all services including historical TLE data and historical GPS almanac data have been restored via https.

Continuing to provide industry-leading tools for our customers is our focus. Thank you for your patience. Contact DME support at 1-800-924-7244 or support@agi.com if you have questions. 

Restored Services: 

• Historical TLE data: *** UPDATE *** The AGI Standard Object Database supports historical satellite TLE data from 1 Jan 2000 to present. 
• GPS almanac data: *** UPDATE *** The AGI Data Server supports GPS Constellation propagation ('Load GPS Constellation' Satellite insertion method) from 7 Apr 1991 09:06:08.000 UTCG to present. 
• For STK version 12.9 and newer; and ODTK version 7.10 and newer: the system used to distribute STK databases and related data (i.e. EOP, space weather, GPS almanac, leap second, satellite TLEs) has been restored at https://data.agi.com/pub/ and https://data.agi.com/dist/ and is directly accessible through the Data Update Utility application installed with the software.
• For STK versions 11.0 through 12.8, and ODTK versions 7.0 through 7.9: the system used to distribute STK databases and related data (i.e. EOP, space weather, GPS almanac, leap second, satellite TLEs) has been restored at https://data.agi.com/pub/ and https://data.agi.com/dist/
  • Modified versions of the Data Update Utility (DUU) application are now available from links in the table at the bottom of this page for STK 12 (applicable to STK 12.0 through 12.8.2), STK 11 (applicable to 64-bit versions of STK 11.0 through 11.7.1), and ODTK 7 (applicable to ODTK 7.0 through 7.9.1). The updated versions will allow automatic access to the https services noted above through the GUI. In order to take advantage of these https services, the user will need to run the updated installer corresponding to the major version of their DME software with admin credentials. This will overwrite the original DUU files installed with the software. To note, this updated version of the DUU will need to be uninstalled separately from STK or ODTK in the future if upgrading or changing versions. 
• Data previously available at ftp://ftp.agi.com/dist/ is now available through https://data.agi.com/pub.
