Ansys STK Software for Digital Mission Engineering and Systems Analysis

Ansys Systems Tool Kit (STK) provides a physics-based modeling environment for analyzing platforms and payloads in a realistic mission context.

Overview

Modeling and Simulating Complex Systems in Their Operational Environments

With Systems Tool Kit (STK), you model complex systems inside a realistic and time-dynamic three-dimensional simulation that includes high-resolution terrain, imagery, RF environments, and 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.

STK CAPABILITIES Ansys STK Puts True Digital Transformation Within Your Reach

Ansys STK extends digital engineering to the mission — the operational environment in which your systems and systems of systems must succeed.

This is digital mission engineering. And while it feels like something that comes at the end of your project’s life cycle — once your system is designed — it’s more than that. Digital mission engineering should be applied early and often, from design through development, test, operations, and sustainment. Uncover problems sooner rather than later and you’ll have a design that excels against your adversaries, ready to deploy far quicker than your competition.

Key Features

Ansys STK boasts an unrivaled collection of multidomain, physics-based analysis capabilities for the aerospace, defense, telecommunications, and other industries

Model Based Engineering

STK provides a framework for representing system of systems architectures by utilizing digital system models to accurately predict mission outcomes and assess a system’s performance and capabilities. With the ability to incorporate models of varying fidelity throughout the engineering lifecycle, STK’s mission simulations and analysis supports the various phases of design, test, and operations as your models mature and evolve.

Communications Modeling

With STK’s communications capability, you can model all the physical components of a system, including the RF environment. Assess the impacts of a wide variety of conditions and interference. Conduct comprehensive link budget analyses.

Radar Modeling

STK’s radar capability simulates system performance in synthetic aperture radar (SAR) or search/track modes. You can model monostatic, bistatic, and multifunction radars in the context of your mission to account for the participation of every asset. Assess the impacts of various conditions and interference on your radar system.

Electro-optical and Infrared (EOIR) Modeling

STK’s EOIR capability models electro-optical and infrared sensors’ detection, tracking, and imaging performance. You can use EOIR to support concept development, design, field-testing, and operations. STK takes this modeling to the big picture by considering electro-optical and infrared performance in conjunction with sensor platform dynamics, communications, and other mission architecture elements to assess integrated performance.

Astrogator

Space professionals have used STK’s Astrogator capability for over two decades to model spacecraft trajectories and reveal mission-critical insights about them. You can use Astrogator to develop, refine, and validate solutions, then return to update subsequent mission stages in response to flight performance. Astrogator’s versatile and modular architecture provides a framework for addressing most spaceflight trajectory problems.

Conjunction Analysis

STK’s conjunction analysis capability comprises four collision threat analysis tools that enable you to detect and assess potential collisions in space and determine blackout times in launch windows and firing time windows for ground-based lasers.

Aviator

With STK’s Aviator capability, you can model aircraft performance, accounting for variations in airframe performance characteristics, wind, and atmospheric effects. Aviator uses realistic maneuvering and flight paths that reflect true flight operations. These operations can be complex — such as a search pattern — or singular, like a barrel roll. With this flexibility, you decide the level of complexity.

Test and Evaluation

Test and Evaluation Tool Kit (TETK) improves the efficiency and effectiveness of test and evaluation activities across the digital engineering product life cycle. With TETK, you can build and validate detailed test plans, monitor test execution, and rapidly analyze post-test results.

Coverage

With STK’s coverage capability, you can extend visibility analysis to discretized, distributed areas, as seen from a collection of assets. Summarize your analysis in terms of traditional metrics such as response and revisit times and abundant customizable qualitative measures.

Analysis Workbench

STK’s Analysis Workbench capability comprises four application-wide tools that you can use to create custom functions and calculations relative to times, positions, and reference frames. It also provides numerous predefined components that can add complexity to your scenarios to help solve your most complex problems.

Integration and Customization

STK includes to two APIs — the Object Model and Connect — that enable you to automate repetitive tasks from outside STK, integrate other applications with STK, access STK’s capabilities from other applications, and develop custom applications. All interfaces are fully documented, and AGI maintains a GitHub repository of code samples to help you get started with the Object Model.

Parallel Computing

STK’s parallel computing capability enables STK to distribute many of its most computationally complex analysis tasks across multiple computing cores on the computer where it’s installed.

The Parallel computing capability also includes software development kits (SDK) for .NET, Java, and Python. These SDKs make it easy to parallelize the execution of custom models and algorithms.

Reporting and Visualization

With STK, it’s easy to communicate your results with customizable reports and graphs, and stunning 3D animations. Visualize entire scenarios in a time-dynamic 3D environment, from geometric components such as pointing vectors and volume grids to 3D models of platforms with dynamic articulations.
