ASTE Licensing of Systems Toolkit

The ASTE Department is an educational affiliate of Analytical Graphics, Inc. ( AGI has granted ASTE students the right to use Systems Toolkit (STK, formerly Satellite Toolkit) free of charge for educational purposes.

USC students taking ASTE classes or participating in ASTE student projects such as Rocket Lab or the Microsatellite Project can obtain an educational license to use STK on their own computers. (STK is a Windows-only program. For use on a Mac or Linux machine, a Windows virtual machine or dual boot must be set up.)

Following are instructions for installing and licensing STK:

  • Download STK Professional from and install it under the demo license.
  • From STK, open the License Manager to display two numbers, the host ID and the registration ID.
  • Email the host ID and registration ID to Dan Erwin, along with the STK version number and the Windows version (XP, Vista, 7, etc.). Additionally, please specify the ASTE course or student project for which you plan to use STK.
  • A machine-specific educational license file will be generated and emailed to you.
