Systems Tool Kit (STK) is the foundation of AGI’s product line. This highly capable, free modeling environment is used by thousands of engineers, mission analysts, and software developers to model complex systems—such as aircraft, missiles, satellites and their sensors—analyze mission simulations and visualize dynamic datasets in 4D (X,Y,Z,Time). STK’s open API, file interoperability and add-on modules can extend these core capabilities, and solutions can be deployed using our software development kits and server product. Finally, STK users can share results such as reports, graphs and HD videos with colleagues, managers and decision makers.
