Analyzing Trajectory & Attitude Profiles in a Custom Coordinate Frame: 

Analyzing Trajectory & Attitude Profiles in a Custom Coordinate Frame Arianne Liepa Application Engineer/Training February 9, 2006

Agenda: 

Agenda Complex geometries in mission analysis Proximity operations Platform attitudes Sensor targeting “Plug-In” and template capabilities Other areas of applicability Question & Answer

Why custom geometries?: 

Why custom geometries? Fundamental analyses Where am I? What direction is that? How far away is that? Geometry types Standard Custom

STK Vector Geometry Tool (VGT): 

STK Vector Geometry Tool (VGT) VGT building blocks Vectors Coordinate frames Planes Compute, analyze, report, display Angles Points Axes

VGT Illustrations: 

VGT Illustrations Proximity operations Coordinate system Relative position vectors Platform attitudes Custom targeting Custom fixed attitudes Sensor targeting Custom pointing schedules

Proximity operations : 

Proximity operations Formation flying: Satellite-centered frame Time-varying relationships Custom geometries: Constellation frame Satellite attitudes Satellite relationships

Model proximity in STK: 

Model proximity in STK Coordinate frame Satellite formation Centered on satellite Relative axes Relative positions Direction Magnitude

Solution using STK: 

Solution using STK Custom coordinate system using VGT 1. Custom coordinate system with CenterSat as center 2. Coordinate system for orbiting satellites

Solution using STK: 

Solution using STK Create Vectors using VGT 2. Display vectors in the 3D window

Custom satellite attitude in STK: 

Custom satellite attitude in STK Custom vectors and axes Targeting attitude Custom pointing vector Custom fixed attitudes “Align and constrain”

Solution using STK: 

Solution using STK 1. Satellite pointing references custom vectors Custom attitude using VGT 2. Satellite attitude references custom vectors

Custom airborne sensor: 

Custom airborne sensor Custom targeting sensors Custom vectors Custom axes

Solution using STK: 

Solution using STK Create custom vectors and axes using VGT

Analytical output : 

Analytical output Reports, graphs, and dynamic displays

Further customization using Plugins: 

Further customization using Plugins Plugin highlights: Custom scripts Analysis and visualization Matlab, Perl, VBScript Select the file here

Poll question: 

Poll question Please take a moment to fill out our poll Do you currently use any of the STK Plugin capabilities below? Select all that apply.  Vector Plugins Constraint Plugins Communication Plugins Other Plugin options (HPOP, Engine models) No, I have never used Plugins Use WebEx to submit your answers

VGT templates: 

VGT templates Reuse geometries Define for object types Apply to any object of that type

VGT in other applicable areas: 

VGT in other applicable areas Astrogator New capability in STK 7 Missile objects Launch coordinate systems Ground vehicles Range vectors to objects Radar Radar pointing vectors

Summary: 

Summary Geometry is important! Custom geometries required for: Proximity operations Platform attitude Sensor targeting STK with VGT is an out of the box solution Building block architecture Flexible Extensible Launch coordinate systems Range vectors to objects
