Our M&S engineering ingenuity is applied to requirements analysis, design, development, and verification, validation and accreditation.
The End-to-End Distributed Development System (ETEDDS) was developed as a collaborative effort between Raytheon Missile Systems and Lockheed Martin to perform high-fidelity system level simulation testing of the Standard Missile-3 (SM-3) and Aegis Weapon System.
Raytheon can connect with its partners, subcontrac tors and competitors in this manner.
In HLA terminology, the components of a simulation are called “federates,” and the collection of multiple federates is called a “federation.” The primary federates within ETEDDS interface directly with the SM-3 missile, the SM-3 kinetic weapon (KW) and the Aegis Weapon System (AWS).
T&E Solutions personnel have performed M&S verification, validation, and accreditation (VV&A) tasking in support of several Navy Programs.
We have led and/or participated in the development of VV&A documentation for the following models and simulations: Verification is the process of determining if Models & Simulations accurately represent the developer's conceptual description and specifications and meets the needs stated in the requirements document.
ETEDDS also plays an important role in flight test preparation for the SM-3 program to help test preparation for the SM-3 program to helpprevent interface errors and to mitigate other live test risks.
Simulated target trajectories based on the flight test scenario definition are fed to the ETEDDS simulation to exercise tactical missile and ship hardware and software in a flight test configuration.
ETEDDS produces a complete set of data for analyzing individual missile and overall system performance by collecting the tactical communication between the launch ship and the missile along with detailed subsystem in-flight performance data.
ETEDDS also tests algorithms under development that may affect systems performance, and it provides a visual representation of the simulation, simplifying and accelerating the assessment of key system attributes.
In the following, the evaluation methods in signal level and function level are described in detail for the model validation.
The model effectiveness is evaluated both qualitatively and quantitatively.
Many of the models we develop are for conceptual designs to support trade-off analyses.
