STK Pro provides a foundation for analyzing and visualizing complex systems in the context of their missions. Create multidomain scenarios that extend simulation beyond systems to an interactive model of the operational environment. Simulate your intended missions and communicate your results with reports, graphs, and stunning 3D animations. Work directly with STK’s graphical user interface or use STK Pro’s robust, documented APIs to automate workflows, integrate with other applications, or create customized tools.

Core functionalities

  • Analysis and Output
