To install Ansys Systems Tool Kit® (STK®) application, you must be an administrator or have elevated permissions for the computer on which the application is being installed. The installation package also includes the Ansys Orbit Determination Tool Kit (ODTK®) application, which requires a separate license.
Supported operating systems
- Windows 11
- Windows 10
- Windows Server 2016
- Windows Server 2019
If you are using Windows Server 2016 or Windows Server 2019, the default browser is Internet Explorer. For the best experience, you should switch to using Microsoft Edge.

Hardware requirements for STK and ODTK software
| Hardware | Requirements |
|---|---|
| Memory / RAM | The minimum is 8 GB; AGI recommends 16+ GB. |
| Disk Space | The minimum is 5 GB; AGI recommends 500 GB depending on your use of supplemental capabilities and data products. Refer to the Supplemental STK Capabilities topic for more information. |
| Graphics Card |
Use a 4 GB (minimum) graphics card that supports OpenGL 4.5 and has updated graphics card drivers. To confirm that your graphics card meets these requirements, check your drivers by opening the Graphics Card Information app from the Windows Start menu (Start > AGI STK ODTK 13.0 > Graphics Card Informtion). If you happen to run into an issue with using your graphics card with the STK application, please refer to Troubleshooting Graphics Card Issues. |
| Network Hardware | The STK application does not require a network adapter, but AGI recommends one. Online operations will not be available without one. |
The STK and ODTK applications can use multiple cores in a computer to improve performance for many computations. Refer to the STK Parallel Computing Capability Overview topic for the list of computations you can perform in parallel using multiprocessing.

Maximizing performance
There are many mission-related factors that impact STK's processing performance for a given scenario, including the following major factors:
- The number of objects in your scenario
- The complexity of your analysis calculations
- The duration of your analysis period
- Your choice of graphics resolution level
Consider these when choosing hardware for your mission analysis needs. For direction on maximizing your specific analysis performance, contact AGI Technical Support.
Virtual environments
You can run STK with accelerated graphics in a virtual environment when it is configured on a computer that meets additional hardware and software requirements. Contact AGI Technical Support.
Connecting to STK online services
For detailed information about how STK connects to the internet, refer to the Network connections for STK online services section of the Online Operations topic.
System requirements for previous versions
If you are running a version of STK that is older than STK13.0, you can still find the system requirements for your version. In your STK installation media (download folder or disk), find and open the "install.chm" file and look for the System Requirements topic in there. For more recent versions of STK, the "install.chm" file is in Support Files > Help.
