ANSYS STK

With STK, you can analyze the performance of complex systems with a focus on their operational environments. Model systems inside a realistic and time-dynamic three-dimensional simulation that includes high-resolution terrain, imagery, RF environments, and much more. Select, build, or import precise models of ground, sea, air, and space assets and combine them to represent existing or proposed systems. Simulate the entire system-of-systems in action, at any location and at any time, to gain a clear understanding of its behavior and mission performance.

For over 30 years, STK has brought the mission into systems engineering.

Transform Your Digital Engineering

Start with a scenario. The scenario is the sandbox of STK’s digital mission engineering environment.

Add models of your systems. Your models can range from low-fidelity stand-ins to full-fidelity simulators. Use your STK scenario to evaluate all your models and their interactions continually throughout the program life cycle.

Analyze your systems in their full mission context. Evaluate all their characteristics — from the position and orientation of individual objects (in any reference frame) to the relative geometry between objects — and their physics-based interactions.

Communicate and decide. Prepare reports and graphs from tens of thousands of measurements in STK. Put it all on display with compelling, precise, 2D and 3D renderings and animations. Leave nothing to the imagination.

STK is available as four different configurations:

In addition, there are three STK Specialized Extensions:

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.
