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

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
