STK ANALYSIS WORKBENCH
Analysis Workbenchstreamlines, organizes,
and extends thefundamental
computational
capabilities of STK.
It contains these application-wide tools:Time Tool. Creates components that
produce instances or intervals of time.
Vector Geometry Tool. Creates componentsthat define location, pointing, and orientationin 3D space.
Calculation Tool. Creates components that
produce various time-dependent quantities.
Spatial Analysis Tool. Creates calculations
and conditions that depend on locations in3D space which are, in turn, provided byuser-definable volume grids.

produce intervals of time within which there
are ordered arrays of times. The times may
or may not be evenly spaced.

Creating components

Vector Geometry Tool(VGT) components•	Select from a large number of installed
components or create custom componentsthat meet your needs.

VGT components deal with time-varying
placement and/or orientation in 3D space
and include the following types:

can be transformed and analyzed further,and include the following types.
Scalar. Defines components that produce
scalar time-varying calculations.
Condition. Defines a scalar calculation,
which is considered to be satisfied when it ispositive and not satisfied when it is negative.

Access components

Axes. Defines orientation and rotationalmotion of a triad of mutually orthogonalunit vectors in three-dimensional space.

Parameter Sets. Defines a set of related
scalar calculations. They can be organized
into multiple nested parameter sets but
each parameter set contains related
calculations which typically represent
various aspects or parameterizationsof one common phenomenon.

A set of components is automaticallycreated for all access objects.

Points. Defines location and translationmotion in three-dimensional space.

Spatial Analysis tool

Time Tool components

Coordinate System. Defines locationand translation motion of the origin andorientation and rotational motion of a triadof mutually orthogonal unit vectors inthree-dimensional space.

Includes the following component types:•	Create custom computationalflows by using the results produced
by some components as inputs forother components.

Time Tool components deal with time related
quantities and include the following types.
Time Instant. Defines components that
produce a single moment in time.
Interval. Defines components that produce asingle interval of time.
Interval List. Defines components that
produce an ordered list of time intervals.
Collection of Interval Lists. Definescomponents that produce a collectionof related interval lists.
Time Array. Defines components that

Vector. Defines direction in 3D space aswell as magnitude.

Angle. Defines angular separation
between two vectors or planes.
Plane. Defines location and translation
motion of the origin and orientation androtational motion of a two-dimensional
plane in three-dimensional space.

Calculation Tool components
Calculation Tool components produce
time-varying computational results which

Spatial Calculation. A calculation that
depends on both time and location.
Spatial Condition. A scalar condition that
depends on both time and location.
Volume Grid. A collection of enumerated
points placed in 3D space, using steps
taken in each coordinate and using various
coordinate types.

Fully integrated with STK
Report and graphs. Any of the installed oruser-created components can be used inreports and graphs.

160111STK ANALYSIS WORKBENCH

Combining spatial calculations and volumegrids in volumetric objects generates reportand graph calculations over time andacross grid points.
All components from Time and Calculation
Tools have on-the-spot, right-click, reporting
options that enable you to generatereports and graphs using all of the relevant
information from the selected component
without first having to create a new style.
Timeline View. Time components can beadded to the Timeline View which provides
another way to display and operate ontime components. They can be added via
the Timeline View menus or dragged anddropped into the Timeline View from theAnalysis Workbench window.
Create data files. You can create external
files of Analysis Workbench components thatcan be imported into STK.
Visualize 2D and 3D time-dynamic
data. Any of the installed or user-createdcomponents can be used to visualize 2Dand 3D time-dynamic data.
Connect and Object Model. Components
can be accessed via the STK Connect
interface, the STK Object Model interface,
and the STK scripting interface which
supports Perl, VB Script and MATLAB.
