Agenda

• Background
• STK/Analyzer
• What is a trade study?
• Implementation
• Functional flow

• Trade studies
• STK/Analyzer advantage
• Summary
• Software licenses
• Questions answers

4
Background

• STK/Analyzer add-on capability to STK

• STK
• Complex software geometry engine
• accurately displays and analyzes dynamic objects
• real or simulated time
• Land, Sea, Air, Space

5
What is STK/Analyzer?

• Engineering tool
• Perform trade studies
• Conduct what if analyses
• Optimize scenarios

6
What is a trade study?

• Gain insight into
• How do results change when a parameter varies?
• Parametric Study
• How do results change when two parameters are
  varied?
• Carpet Plot
• How are results bounded by a table of input
  values?
• Design of Experiments
• What will this uncertainty in inputs do?
• Probabilistic Analysis
• What do I need to do to optimize certain things?
• Optimizer

7
STK/Analyzer implementation

• STK module
• Separate license
• Separate install CD (or download)
• Separate executable
• Opened from within STK
• Requires STK up and running, with scenario open
• Links from Welcome page or Scenario menu

STK/Analyzer functional flow

Trade studies

• Parametric Study
• Vary one parameter

• Example How does coverage change versus sensor
  detector pitch?

• Example How does required Dv change versus true
  anomaly of burn start?

• Example How does coverage change versus
  inclination?
• Vary inclination and look at coverage statistics

10
Trade studies

• Carpet Plot
• Vary two parameters and see what happens
• Example How does coverage change if inclination
  and semi-major axis are allowed to change?

11
Trade studies

• Design of experiments
• Vary several parameters and see what happens
• Runs a table of cases
• Useful for running all kinds of boundary
  conditions

12
Trade studies

• Probabilistic analysis
• Monte Carlo study
• Vary input parameters according to expected
  probability
• Example A launch vehicle will give a certain
  set of drop-off conditions with known
  distributions. What will that mean to the final
  orbit?
• Output
• Tables
• Distribution profile
• Scatter matrix

Trade studies

• Optimizer
• Vary parameters to find the best solution

• Example Vary transmitter frequency, data rate,
  and power in order to get the highest minimum
  Eb/No
• Example Determine the optimal position to
  minimize fuel for a maneuver

16
STK/Analyzer advantage

• Eliminates time-consuming, manual what-if
  analysis
• If done by hand, probably not exhaustive
• Allows user to truly understand the design space
• Eliminates need to script/write code
• Easy-to-use GUI
• No need for MATLAB proficiency
• No in-house code to maintain
• Allows user to optimize scenario
• Min, max, or specific value

17
Summary
STK/Analyzer is the difference between Having a
solution vs. having the best solution
