Northrop Grumman Corporation has been awarded a contract to provide a Combat Electromagnetic Environment Simulator (CEESIM) system to support maintenance of the U.S. Air Force E-3 Airborne Warning and Control System (AWACS) Electronic Support Measures Operational Computer Program software.The CEESIM provides navigation and pulse data generated from customized scenarios. It enables ASIF software engineers to model a real-world environment and to test software changes by injecting pulses into the avionics hardware.The AWACS CEESIM system will replace an Advanced Multiple Environment Simulator (AMES) system that has been operating at Tinker Air Force Base for 14 years. The CEESIM replacement unit allows automatic conversion of legacy AMES emitter files to CEESIM emitter files for seamless reuse of AISF threat data and test scenarios. The simulator also demonstrates the CEESIM versatility allowing for direct stimulation using radio frequency, intermediate frequency and digital outputs.Learn more from Northrop Grumman.
