What’s new in STK version 12

STK is an essential tool for analyzing and visualizing complex systems in the context of your mission.

Swiftly interact with data from platforms across aerospace, defense, telecommunications, and other

industries. Simulate your intended missions under non-homogenous conditions and communicate

the results with reports, graphs, and stunning 3D animations.

STK 12

continues the evolution of AGI’s mission simulation platform, which supports digital mission

engineering and digital mission operations workflows.

Here are a few of the capabilities introduced in STK 12:

Aviator

Basic Maneuvers now use a full 3D gravity model with oblate rotating Earth effects,

including Coriolis terms. STK 12 also adds a Lambert midcourse guidance strategy for interceptor

engagements. And, you can now automate Aviator with a rich API supported by the STK Object

Model.

EOIR

STK 12 introduces cloud modeling with a flexible, thin-layer approach. This capability

supports inputs for multiple time-dynamic layers and cloud characteristics such as percent cloud

cover, temperature, emissivity, and

radiance. Meanwhile, under the hood,

EOIR has been converted from a UI

plugin architecture to become part of

the core STK Engine.

3D Tiles and Lighting Analysis

3D Tiles are known for visualization in STK,

but now you can use them in analysis

to constrain line-of-sight access.

Lighting analysis in STK has also been

improved in STK 12. You can include

the effects of terrain on vehicles and

objects in lighting computations.

Communications

You can now import antenna-gain patterns generated by Ansys HFSS in the

.ffd file format. An individual .ffd file may include multiple gain patterns. Also new to STK 12, RCS

contour lines — for antennas, transmitters, receivers, radars, and vehicles — now display atop 3D

terrain when not displayed at altitude.

Parallel computing

The number of default local cores for parallel computing in STK has been

increased to eight. STK can use more cores with additional licensing. Also new to STK 12, the STK

Parallel Computing Server SDK is available in Python. Finally, you can now save scenarios and

VDFs in a binary format, which decreases loading time for the parallel workers.
