What’s Coming in STK 102D Map Improvements

Background STK 3 through STK 9– 2D map graphics drawn using a layered approach Device independent layer Device rendering layer– Rendering layer based on Microsoft GDI (GraphicsDevice Interface)– Graphics card accelerated on Windows XP dependingon card and driver and to a certain degree on Windows7, but not on Vista– Limited on effects such as translucency, blending,texturing

Background STK 10– Rendering layer replaced with OpenGL-basedInsight3D rendering– Fully accelerated using modern rendering techniques– All OpenGL capabilities available for user’s video cardand driver

Imagery Updates Bing maps now free in STK Basic 2D map supported formats now include:– Bing maps with LOD switching for zoom/pan– GIS data via Esri mxd files as image inlays– jp2 and pdttx as background images Effects– Mipmapping used to smooth imagery– True translucency for overlapping images

General Features Pan Mouse wheel zoom in/out True translucency for imagery, sensor andarea target fill, coverage On/Off toggle buttons in object browser Color Selector in object browser Sun Lighting effects

Coverage Changes OverviewUse of Insight3D renderer in 2D enables largeperformance gains in both 2D and 3DCoverage graphics layer modified toimprove:– Smooth contour rendering performance in 2D and 3D– Displaying of block contours over terrain in 3D– Displaying of smooth contours at altitude in 3DCoverage graphics GUI changed for usabilitywith new 2D/3D options

Coverage Smooth ContoursNatural neighbor interpolation now computedusing graphical method with VoronoidiagramsData computed only when grid definitionchanges and storedDynamic texture updated each animationstep from Voronoi diagram data and FOMgrid point values

Coverage Display at Altitude in 3DTriangle meshes used to display results ataltitudeSurface meshes used to display results overterrainMeshes will be textured when smoothcontours are used and simply colored forblock contours

New and Improved Tools in STK 10 Motivation– Better leverage STK computational engine standardize common computational types increase connectivity between computations provide ability to derive new computations at runtime– Improve debugging and provide in-depth validation– Streamline retrieval of results– Facilitate task-oriented workflow

Geometric Components Vector Geometry Tool (VGT)– Encapsulates time-dynamic geometric computations –core of STK computational engine– Computational types Axes, Vectors, Points, Systems, Planes, Angles– Many VGT components are installed out-of-the-box 94 for default Satellite– Users can add components using operations onexisting components existing components - from other objects and other tools (Timeand Calculation), both installed and user-created components 66 operations

Time Components Time Tool– Encapsulates time related computations – core of STKcomputational engine– Computational types Time Instant, Interval, Interval List, Collection of Interval Lists,Time Array– Many Time components are installed out-of-the-box 13 for default Satellite– Users can add components using operations onexisting components existing components - from other objects and other tools (VGTand Calculation), both installed and user-created components 30 operations – time shift, logical, times of extremum,satisfaction times, etc.

Time Components Timeline View– Dedicated window for display of Time components Multi-line display Scrollable and zoom-able Animation marker and custom annotation markers Multiple stored views

Calculation Components Calculation Tool– Encapsulates most other computations and providesalgebraic, functional and calculus operations– Computational types Scalar, Condition, Collection – Attitude, Trajectory, Orbit,Vector, Ground Trajectory, Data Providers– Many Time components are installed out-of-the-box– Users can add components using operations onexisting components existing components - from other objects and other tools (VGTand Time), both installed and user-created components 20 operations – algebraic operations, elementary andpolynomial functions, integral and derivative, etc.

Streamlining Reporting and Graphing STK Data Providers and Report Manager– Reports and Graphs are based on styles Styles describe which data provider elements should beincluded Many styles are installed New styles can be created within Report Manager VGT, Time and Calculation components (installed and usercreated)are automatically available as data providers Reporting and Graphing directly from Timeand Calculation tools– Report and graph styles are generated on-the-fly– Can be saved to Report Manager if needed

Object-Centered Approach Advantages– Typically few objects with straightforward relationships Parent-child, Access from-to, Assets or grid points in Coverage– Natural for visualization– Default object configurations work well for typical users Limitations– Most objects are complex with many configurationparameters– Need in-depth knowledge of object design to identifyrelevant parameters and data provider elements– Difficult to add new computations or create newcomputational pathways

Alternative to Object-Centered Approach Advantages– Computational components are simple and have clearrelationships Vector cross product, Elevation angle, Times when elevationangle above threshold, etc.– Easy to add new computations and create newcomputational pathways– Easy to debug and obtain results from individualcomponents Limitations– Many components with many connections may beneeded

Summary STK new approach– Retain object-centered approach for typical problems– Expand computational capabilities to solve newproblems using new computational components andtools Have each object provide various computational components Use new computational tools to manipulate and create newcomponents as well as report/graph and visualize their data
