STK continues to enhance integrations across Ansys multiphysics solvers, such as Ansys Fluent and STK’s Aviator capability to define higher fidelity aircraft trajectories while considering the effects that an aircraft platform geometry may have on the overall aerodynamics and performance capabilities. Users can also leverage a new radar clutter modeling capability, which introduces an open architecture of plugin capabilities that enable users to define clutter models and evaluate the impact on a radar’s ability to resolve target objects within the modeled environment. In addition, spacecraft trajectory designers using STK’s Astrogator capabilities can now take advantage of enhanced Python scripting supported in this latest release.
This latest release also provides developers and system integrators with expanded documentation to support containerization efforts for custom STK Engine applications. Deploying applications through containers can now be supported on both Windows and Linux.
2023 R1: STK 12.6 and ODTK 7.6
STK 12.6 New Features
Enhanced Radar Clutter Modeling
With this latest release, STK’s approach to incorporating and modeling radar clutter effects has been consolidated to make it easier for users to introduce clutter effects and consider their impacts on their modeled radar’s performance.
This update enables users to define the clutter source locations as well as the scattering properties of the geometry. In addition, users can introduce a list of clutter sources to be included and considered by the radar system. These clutter definition models can also now be defined as centralized components through the STK Component Browser. so that other modeled systems can easily reference them.
Enhanced Python Support for Astrogator
The Astrogator scripting tool is a powerful mechanism for augmenting workflows within Astrogator. The addition of native support for Python scripting within this framework enables the possibility to leverage existing Python modules and represents a convenient option for users already versed in the increasingly popular Python language. Additionally, pre-installed Python wrappers for all Astrogator plugin points enables new, powerful plugin workflows that do not require registration within Windows or administrative privileges on the computer.
Enhanced Aviator Modeling
Fluent Interoperability Enhancements
TETK Scripting Tool Improvements
Integrated EOIR Thermal Model Loading from Aviator
Sensor system designers must be able to accurately simulate conditions under which their sensors will be expected to operate and perform. This release of STK introduces a new capability for EOIR sensor definitions that enables users to directly link to an aircraft target object’s thermal load as produced by STK’s Aviator flight modeling capability. Aircraft designs and mission profiles can now provide the thermal loading results directly to the EOIR sensor models, reducing the need to export results, post-process, and reintroduce them to the sensor model for inclusion.
This new capability now shows up as a data provider option that has been added to the temperature option when defining an EOIR sensor’s target shape property files. This enables EOIR users to specify the Aviator thermal load model as a data source.
Containerized Engine Applications (Windows)
Containerized applications offer great benefits to engineering organizations that leverage the customization options provided by STK. Using STK’s backend engine along with automation APIs, users can containerize their custom applications, making them easier to deploy and minimizing the amount of time and effort required to provision compatible systems. With this latest release, STK provides supporting documentation for Windows containers in addition to the existing support for Linux.
