Northrop Grumman has announced the delivery of Combat Electromagnetic Environment Simulator (CEESIM) systems and a Signal Measurement System (SMS) to Aselsan, the Turkish high technology defense electronics company based in Ankara.

In three separate contract awards, Northrop Grumman was selected to provide a CEESIM, an SMS and a Pulseman Portable CEESIM Simulator to Aselsan's Radar, Electronic Warfare and Intelligence Systems Division to support various electronic warfare (EW)-related programs within Turkey.

Aselsan provides EW equipment for use on ground-based, naval, fixed and rotary-wing platforms.

"Together, CEESIM and SMS offer a complete end-to-end electronic warfare testing solution by providing Aselsan the ability to generate a highly realistic simulated environment while measuring how well the EW equipment operates within that environment," said Joe Downie, president of Northrop Grumman's Amherst Systems business unit.

"The Northrop Grumman CEESIM system is the most advanced radio frequency (RF) simulator on the market today," noted Downie.

CEESIM generates complex dynamic electromagnetic environments that allow users to test and evaluate the performance of advanced electronic warfare systems including radar warning receivers, electronic countermeasure systems and signal intelligence systems.

CEESIM is fully reprogrammable and is able to simulate EW/radar signals and communication signals.

The Signal Measurement System provides real-time RF measurement and analysis of threat emitters and corresponding system-under-test jammer responses for hardware-in-the-loop, installed system, and open-air training range applications.

The CEESIM and SMS systems were delivered in early spring 2011, followed by the delivery of the portable version of CEESIM in September, bringing to seven the total installed base of RF simulators in Turkey.
