Combat Electromagnetic Environment Simulator (CEESIM)

Delivering the Most Advanced Simulation Architecture and Capability

CEESIM unit showcasing advanced radio frequency environment simulation capabilities for true-to-war testing conditions.

CEESIM Faithfully Simulates True-to-War Conditions

The most advanced electronic warfare systems begin with CEESIM, the most advanced radio frequency (RF) environment generator. CEESIM creates true-to-war conditions, so your RF systems are tested and proven on Day One.

See the Threat, Defeat the Threat

CEESIM simulates multiple, simultaneous emitters linked to static and dynamic platforms, creating a faithful representation of true combat conditions to accelerate RF system development. These robust simulations offer the most affordable and rapid means of testing and validating the effectiveness of sophisticated electronic warfare equipment.

Our modular, software-defined/hardware-enabled CEESIM technology keeps pace with changing threats to provide the ultimate ongoing mission support so warfighters can maintain the tactical advantage in the electromagnetic battlefield. Our unmatched depth in simulation systems has kept CEESIM users at the forefront of RF system development for decades.

Visualize the invisible with SimStrike™

Modeling RF signals in congested electromagnetic spectrum environments is no easy task. With SimStrike™, the visualization tool for CEESIM, users can see the most complex RF signal environments.

SimStrike™ gives engineers 3D scenario visualizations of threat laydown, platform and emitter positions, and RF pulse counts. Multiple emitter views provide parametric data, including frequency, PRI, pulse width, and scan characteristics, to allow for precision tuning of waveforms and techniques. Real-time playback of intel collection data allows immediate testing against new threat waveforms to allow for rapid evolution of countermeasures. Open Application Programming Interfaces (API) support the integration of user-supplied threat models, tools. and data.

CEESIM’s Scalable Architecture: Adaptable, Affordable and Ready When You Need It

CEESIM scales to fit your mission, with truly modular packaging designed around your needs. Unlike commercial off-the-shelf synthesizers and similar components that require costly tailoring and retrofits to meet simulation requirements, our modern CEESIM architecture uses common building blocks for rapid scalability and affordability. Need more capability? Simply stack Compact CEESIM VPX units to boost capacity.

A Complete, Multi-Spectral Lab Environment

Our Real-Time Infrared Electro Optic Scene Simulator (RISS) product encompasses an integrated software and hardware solution to provide high-fidelity, real-time, reactive imagery for test and evaluation systems in both hardware-in-the-loop and man-in-the-loop configurations. RISS operates stand alone or seamlessly integrates with CEESIM to create a complete, multi-spectral lab environment.

Robust test facilities require synchronized multi-spectral signals (RF, IR, EO) under coordinated control (along with and data logging) in order to test and evaluate modern systems employing both on-board and offboard technology. SCS synchronizes the CEESIM, RISS and other simulation equipment for a complete multispectral test environment.
