AbstractThe capability to model, simulate, and analyze projected operationalmissions for new and potential weapon systems is critical to sellingthose systems to customers.The Satellite Tool Kit suite of software is being used to simulate andanalyze both tactical and strategic systems in representative operationalenvironments. Clear three-dimensional visualizations and quantitativeanalyses allow the demonstration and evaluation of the effectiveness ofnew systems in achieving mission objectives.This simulation and analysis capability improves the developer’s strengthas a system integrator, and facilitates the establishment of systemrequirements, validation of system designs, and will allow simulatedinteraction between new or proposed systems and other military assets.www.stk.comPg 2 of 15

Role of Operational MissionAnalysis & Simulation• Assess Proposed/Evolving Design– Exercise proposed solutions in simulated missions to see how they meetcustomer defined needs and mission objectives– Generate data for system design, mission planning & support planning• Evaluate Figures of Merit against System Requirements & MissionObjectives– Assure requirements flow from customer need & mission objectives– Assess mission effectiveness measures & system robustness (flexibility)• Predict/Validate System Performance– Gain better understanding of system operational potential & limits– See how well the system performance satisfies system requirements• Educate Users and Market the System– Show stakeholders how the system meets their needs– Demo new concepts of operation for entirely new systems– Demo system capabilities to potential customerswww.stk.comPg 3 of 15

Simulation Addressed OperationalIssues• STK Simulation Allowed Rapid Definition of EngagementGeometry & Timing– Impact of target range, airspeed, banking angle on sensor FOR• Example - Initial proposed engagement pattern put targets outsidesensor Field Of Regard– Impact of different sensor and laser mounting locations & sensorrotation rate on engagement windows & mission effectiveness• Computer Simulations Validate System Performance– Mission Effectiveness - How Many Kills? Do Kills Occur On-Time?Able to Prevent Alarm? Provide Enough Close Air Support?– Robustness - Variations in Aircraft/Weapon Design, Variations inWeather, Variations In Threat Responsewww.stk.comPg 10 of 15
