Combat Electromagnetic Environment Simulator (CEESIM)

Combat Electromagnetic Environment Simulator (CEESIM)

Delivering the Most Advanced Simulation Architecture and Capability

Northrop Grumman's CEESIM faithfully simulates true-to-war conditions.

When it comes to development and operational testing, an accurate model of the electromagnetic spectrum is a must. High fidelity simulations of the congested, contested environment provide the most cost-effective means of testing and validating the effectiveness of sophisticated electronic warfare equipment.

Our modular, software defined – hardware enabled technology keeps pace with changing threats to provide the ultimate ongoing mission support—so your warfighter can maintain the tactical advantage in the electromagnetic battlefield.

Simulating the Battlefield in an Electromagnetic Environment

CEESIM provides the radio frequency (RF) simulation of multiple, simultaneous emitters linked to static/dynamic platforms required to faithfully simulate true combat conditions. Robust simulations offer the most affordable means of testing and validating effectiveness of sophisticated electronic warfare equipment.

Powerful Tools Maximize Productivity

CEESIM includes a set of powerful tools for threat and scenario programming and validation. The entire User Experience is optimized for ease of use and operator efficiency. Visualization tools help the user validate waveform programming and scenario laydowns. A new “drag-and-drop” tool allows the operator to utilize a predefined palette of radar task waveforms to quickly create complex variably framed emitter waveforms. The Maintenance application provides graphical status at the line replaceable unit (LRU) level and guides the operator through calibration procedures when required. Multiple import capabilities speed emitter and scenario development through direct access to intelligence databases and standard model outputs. Real time playback of intel collection data allows immediate testing against new threat waveforms. Open Application Programming Interfaces (API) support integration of user supplied threat models.

An Adaptable, Affordable Solution, Ready When You Need It

When it comes to preparing fighters for the current and future electronic warfare environment, only Northrop Grumman offers a proven solution implemented in truly modular packaging that keeps long-run costs in check. Unlike commercial off-the-shelf (COTS) synthesizers and similar components that require costly tailoring and retrofits to meet simulation requirements, our modern CEESIM architecture has the same advanced threat performance you trust, but with new building blocks that allow you to build small or large systems to fit any budget with a short delivery timeline. Full fidelity simulators can be delivered in as little as two months.

Northrop Grumman offers multiple configurations of the CEESIM technology to meet the distinct needs of your many missions. Core system building blocks are implemented in a VPX form factor that builds on existing CEESIM capabilities. These building blocks are utilized to create a wide range of system configurations based in individual customer test requirements. This flexible architecture allows us to provide the minimum hardware needed to meet test requirements for the most cost-effective solution. The plug-and-play design supports easy expansion in the field. Compact CEESIM-VPX offers full CEESIM capability in the space of a COTS synthesizer.  CEESIM-VPX is scalable to meet a wide range of test requirements.


Proven Experience in the Electromagnetic Environment

Northrop Grumman has a legacy in the art and science of RF simulation and the electromagnetic environment. With more than 60 years of experience in the development and delivery of offensive and defensive systems. Northrop Grumman's capabilities in electronic warfare, full spectrum cyber and electromagnetic warfare span all domains – land, sea, air, space, cyberspace and the electromagnetic spectrum.

Advanced Pulse Generation

With CEESIM's most recent technology evolution, Advanced Pulse Generation, high speed direct digital synthesizer (DDS) technology is used to generate realistic EW and Communication, Navigation, and Identification signal environments that can be simulated with a variety of complex modulation on pulse characteristics. APG functionality provides significant advantages, including higher modulation sample rates, wider bandwidth intrapulse modulation, higher precision and resolution, and reduced calibration time.

What is Electronic Warfare?

The military uses the electromagnetic spectrum — essential, yet invisible — to detect, deceive and disrupt the enemy while protecting friendly forces. As enemies become more capable and threats more complex, controlling the spectrum is increasingly critical.
