AGI Systems Tool Kit (STK) 11.2

ای جی آی سیستم تول کیت

AGI Systems Tool Kit (STK) is a physics-based software geometry engine that accurately displays and analyzes land, sea, air, and space assets in real or simulated time. Users can model the time-dynamic position and orientation of these assets via various propagation algorithms or external inputs.

Given these dynamic positions and orientations, users can model the characteristics and pointing of sensors, communications, and other payloads aboard the asset. STK can then determine spatial relationships (e.g. line of sight) between an asset of interest and all of the objects under consideration across multi-hop links or over regions and volumes of interest.
- Streaming Terrain
You can now stream worldwide terrain for both analysis and visualization from AGI’s publicly hosted STK Terrain Server. The visualization is included with STK for free and the analysis is included with the corresponding licenses for terrain calculations. Furthermore, you can populate the STK Terrain Server with AGI's pre-processed terrain, along with your own private terrain data, to create a blended terrain mosaic with an online subscription or as an offline product for delivery on a private network.

- Volumetrics
Volumetrics combines the flexibility of the analysis workbench with the spatial analysis capabilities of coverage. You can define a variety of 3D volumetric grids in any coordinate system, even if those coordinate systems are attached to moving objects. You can then apply spatial calculations throughout STK (including the new features in STK 11 such as phased array) to those volumetric grids. The new Volumetric object type allows you to manage these grids and spatial calculations and apply display settings to allow you to visualize your dynamic volumes of interest, including grid point settings, isosurface values, and translucency. Furthermore, you can import your own data for volumetric analysis and visualization.

- Phased Array
The new phased array antenna type can be used with both STK Communications and STK Radar to model a variety of new mission scenarios, including GPS Jamming, electronic warfare, and communications interference. The phased array antenna type allows you to specify the physical aspects of the antenna elements, using several standard layout types or user supplied data. Furthermore, the antenna beam direction and/or nulls may be defined based on STK objects, user supplied data, or plugin scripts. Additionally, you may select various beam and null steering algorithms including MVDR or custom plugin scripts, which compute the weights for each of the elements. These weights are then used to compute the antenna’s gain pattern, which can then be applied to STK Communications and STK Radar calculations.

- Aviator
Aviator is the next generation of Aircraft Mission Modeler, which provides an aircraft route-planning and design tool-set ideally suited for performing complex, highly accurate, time-dynamic analysis for both mission planning and operations, as well as aircraft systems design. Aviator now includes the ability to model fixed and variable wind speed effects on aircraft performance, additional procedures for modeling a variety of commonly flown aircraft route types, and a significant number of usability improvements. Aviator Pro is an extension of Aviator that allows you to model more advanced procedures by providing a selection of real guidance strategies relative to other aircraft, including intercepting moving targets, flying a constant relative bearing, orbiting a point relative to other objects, or maintaining formation with a cooperative aircraft.

- EOIR
STK EOIR includes a multitude of improvements that provide more flexibility and fidelity for modeling detection, tracking, and imaging performance of electro-optical and infrared sensors. Applications include space situational awareness, missile defense and remote sensing. Most notably, EOIR now supports the MODTRAN atmospheric model. Additionally, users can now apply custom 3D models, materials, and temperature profiles. Finally, EOIR sensors have been integrated as a new sensor type in STK, which allows for object model support and access to analysis workbench components.
