Our Company
JESSIX is a woman-owned small business specializing in commercial software development with over 30 years of experience in creating air missile defense simulation software. We deliver innovative solutions for the space, air, and missile defense (AMD) community using modern architecture.
In 2020, JESSIX introduced Xyloni, a TRL 9 plug-and-play constructive simulation that integrates live and virtual systems. This interactive simulation features built-in systems, a detailed terrain map, and a global airport/runway database for seamless takeoff and landing. Proven in exercises conducted in 2023 and 2025, Xyloni allows for rapid scenario creation and provides non-proprietary data outputs that can be shared freely with government agencies, while its source code remains proprietary to JESSIX, certified for NIST 800-53 SA-15. Additionally, Xyloni connects directly to decision-making applications.
Xyloni Performance
Unlike traditional AMD software developed on outdated architectures, Xyloni leverages Windows 11 .NET Core to deliver advanced live/virtual/constructive (LVC) simulations. It successfully integrates numerous platforms with thousands of entities, achieving 98-99% accuracy without crashes, as demonstrated in 2023 and 2025. Xyloni has been recognized as “as real world,” outperforming many GOTS/COTS solutions in interoperability and features during large-scale exercises.
Support & Training
With JESSIX’s annual subscription model, users benefit from rapid updates and bug fixes within months. Xyloni includes a one-week training program that enhances warfighter air defense knowledge, allowing results to be extracted and evaluated during or after an exercise, unlike competitors that often require weeks for similar training. JESSIX staff lead simulation support for exercises, offering expertise in planning, network setup, tactical communications, and global scenario implementation without significant network changes, including connecting simulations to tactical equipment for exercise execution.
Our Expertise
With extensive experience in simulation software design and integration, JESSIX ensures effective training and testing. We develop high-fidelity LVC software rapidly, delivering real-world air missile defense simulation solutions that exceed other AMD simulations in both realism and performance.
