Simulate The Future, Innovate With Precision

Replicant™ is a powerful digital twin simulation platform designed to model and test complex systems across air, space, sea, and land domains. It integrates high- and low-fidelity models in a scalable, modular environment, enabling realistic end-to-end simulations, including Hardware-in-the-Loop (HiL) capabilities, for applications ranging from satellite constellations to global ground networks.

What Does Replicant™ Do?

Replicant provides a multi-fidelity simulation environment that seamlessly integrates complex high-fidelity models, such as instruction-accurate emulations of flight processors, with low-fidelity models like MATLAB or Python scripts. With its advanced capabilities, Replicant enables users to create realistic end-to-end system digital twins encompassing ground, space, and user segments, all within a unified environment. Developed under the DARPA Faithful Integrated Reverse-engineering and Exploitation (FIRE) program, Replicant is built with scalability, modularity, and usability as key design principles.

How It Works

Replicant incorporates high-fidelity physics modeling for multiple domains, leveraging tools like Basilisk for space simulations. Its intuitive workbench GUI allows users to drop in, connect, and design systems from models as needed, while supporting realistic command and control (C2), RF channel simulations, and space link protocols.

The platform also supports Hardware-in-the-Loop (HiL) mode. This includes FPGA designs, enabling users to replicate single satellites or entire constellations with global ground networks in a combined simulation environment. With many-on-many simulation capabilities, Replicant provides unparalleled flexibility for testing and validating complex systems.

Key Features Of Replicant™

Scalability

Replicant is built on a robust Kubernetes micro-services architecture, offering a web-based interface that can run locally or in the cloud. Its scalability and modular design make it suitable for a wide range of applications, from classified environments to competitive challenges.

Graphical Assembly

Simplified process of building and managing simulations by providing a user-friendly, flow graph-style graphical user interface (GUI). Instead of requiring extensive coding or technical expertise, users can visually assemble and connect components, systems, and models in an intuitive drag-and-drop environment.

Interchangeability of Models

Users can seamlessly swap out one model for another, as long as the models share the same interfaces. This means that components within a simulation can be replaced without requiring extensive reconfiguration, provided they are designed to communicate and interact in the same way.

Mixed Fidelity Library Of Models

Users can flexibly swap between complex, high-fidelity models and simpler, low-fidelity ones based on the specific needs of their simulation. This adaptability ensures efficient resource use while maintaining the accuracy required for the task at hand.

Proven Performance

With its proven track record in DARPA programs and high-stakes competitions, Replicant is the ideal solution for organizations seeking advanced simulation and modeling capabilities.

Example Use Case: Hack-A-Sat

Hack-A-Sat is a cybersecurity competition created to expose and address vulnerabilities in Department of Defense (DoD) satellite systems. The initiative began with a bold idea: prove that satellites can be hacked, and then learn how to defend them.

• Why it started: Satellites are critical to national security, yet they remain vulnerable to cyber threats. Hack-A-Sat was launched to identify weaknesses and strengthen defenses.
• The competition: Over four years, the event evolved into one of the most challenging hacking contests in the world. The DoD partnered with Cromulence (now a part of Parsons Corporation), a team renowned for running DEFCON’s cyber competitions for five consecutive years, to design and manage Hack-A-Sat.
• Historic milestone: In 2023, Cromulence launched a spacecraft into orbit, and for the first time, the competition took place in space—hackers were challenged to interact with a live satellite.
• Next phase: To prepare for future challenges, Cromulence leveraged Replicant to develop and test real satellite systems. Competitors were run against the Replicant satellite, enabling safe, high-fidelity simulations before engaging with hardware in orbit.
