Problem
JNWC needs a tool that is…
– Easy to use (Reading in data, processing results)
– High Fidelity (Yields accurate predictions)
– Eye Pleasing (You can “see” what is happening)
– Common among all users (Repeatable results)
– Built to support all phases (Preflight, Real-time, Post)
– Built to support all missions (EA, ES, and EP)
Pg 5 of 15AGI www.agi.com
Needs – Pre-flight
• Perform Preflight prediction analysis– Mission Planning (Jammers / Routes placement)
• Power Levels• Assets in view• J/S contour• Predicted Nav solution
Pg 6 of 15AGI www.agi.com
Needs – Real-time
• Provide Real-time Situational Awareness– Data streaming from TSPI, TIBS, FAA, Comm links
• Positions, Collected data, performance data
– Projected data calculated via models• Power levels, In-view analysis, theoretical performance
Data – Strip Charts
3-D Situational Awareness

Pg 7 of 15AGI www.agi.com
Needs – Post-test
• Perform Post Test analysis– Comparison results / analysis
• Truth (TSPI) versus Measured (calculated)• Predicted (models) versus Measured (calculated)
– Points of Interest Drill Down• Vulnerability Assessments / TTP development / Reports
