ETEDDS provides a cost-effective integration approach using an infrastructure to integrate multiple simulated systems in geographically different locations (each contractor uses their own existing facilities).
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.
In 2008, Raytheon engineers used ETEDDS to rapidly test modifications to a special SM-3 missile tailored to destroy a damaged satellite in a decaying orbit.
The dead satellite was traveling 17,000 miles per hour and the team had a 15-second window on each of a total of seven days to shoot down the satellite.
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).
Having simulation components separated by large distances does present some challenges, especially regarding network latency.
ETEDDS has devised technology and methodologies to mitigate network latency issues and yet allow the connected components to operate in real-time.
The combined weapon system provides sea-based protection against ballistic missile attacks.
There is a critical need for testing of the entire weapon system to find potential integration issues and other issues prior to expensive flight testing.
Other federates route threat information, collect data, visualize scenes, control simulation components, store information in a database, and analyze data (see Figure 2).
