To keep this defensive system operating at maximum effectiveness, the Army periodically updates the software on the more than 1,000 AN\/AAR-57 units in use around the world.\u003C\/p\u003E\u003Cp\u003EBefore new updates are fielded, however, they must be thoroughly tested to make sure the software performs as expected. Thanks to collaboration between researchers at the \u003Ca href=\u0022http:\/\/www.gtri.gatech.edu\/\u0022\u003EGeorgia Tech Research Institute\u003C\/a\u003E (GTRI) and the Army Reprogramming Analysis Team (ARAT), that testing can now be done in a new integrated support station (ISS) that puts the software through its paces under conditions simulating actual aircraft operation.\u003C\/p\u003E\u003Cp\u003EUsing a standard AN\/AAR-57 system unit and associated sensors, the new ISS allows the Army to test software updates under a wide range of scenarios and conditions to make sure it will perform as expected on Army aircraft.\u003C\/p\u003E\u003Cp\u003E\u201cThe ISS creates an environment by feeding data to the sensors, simulating threats and monitoring the responses that the unit makes to the simulated threats,\u201d said William Miller, a GTRI senior research scientist who leads the project. \u201cThe ISS then correlates the results to make sure the system\u2019s responses are what should be expected from the threat information fed into the system.\u201d\u003C\/p\u003E\u003Cp\u003EThe ISS development was part of a multi-phase program that transferred sustainment of the AN\/AAR-57 software from the system\u2019s original equipment manufacturer to the Army. GTRI has been involved in the effort since 2010, working closely with ARAT program staff and leaders housed on the Georgia Tech campus in Atlanta.\u003C\/p\u003E\u003Cp\u003EDevelopment of the new AN\/AAR-57 ISS involved software development, system documentation and reverse-engineering of the 1990s-era components where documentation no longer existed. Project goals also included addressing system obsolescence issues in the original ISS units.\u003C\/p\u003E\u003Cp\u003E\u201cAs a result of this project, the Army now has a complete process that they can follow based on the research we did with them over the past four years,\u201d Miller added.\u003C\/p\u003E\u003Cp\u003EMissile attacks on low-flying helicopters typically take place over a short period of time, so the unit has to perform rapidly and at top efficiency. Once activated, the AN\/AAR-57 can operate automatically without intervention from the crew.\u003C\/p\u003E\u003Cp\u003E\u201cA missile warning system looks at the environment, picks up potential threats, and over a very short period of time determines whether or not there is an actual threat approaching an Army rotary-wing or fixed-wing aircraft,\u201d Miller said. \u201cIf the system determines that there is a threat, it controls the dispensing of countermeasures. This happens so quickly that a pilot would not be able to detect the threat manually or respond manually.\u201d\u003C\/p\u003E\u003Cp\u003EThe project produced three ISS units. Two of the units have been delivered to the Army\u2019s Aberdeen Proving Ground laboratories, where they are already in use. A third unit now at ARAT\/GTRI\u2019s Atlanta laboratories is scheduled to be delivered in the fall.\u003C\/p\u003E\u003Cp\u003EThe project involved nearly 60 GTRI researchers at various stages of the work. Now that the three ISS units have been built, the researchers are working on other aspects of support for the Army\u2019s AN\/AAR-57 \u2013 including development of the next-generation of ISS. The AN\/AAR-57 is used on the CH-47 Chinook, UH-60 Black Hawk and AH-64 Apache helicopters, and on various fixed-wing platforms.\u003C\/p\u003E\u003Cp\u003EThe location of ARAT staff and leadership on the Georgia Tech campus has created a unique collaborative environment in which advances can be made quickly. \u201cBecause we are working side-by-side with them, we are in constant communication about the needs of the Army and how we can efficiently support their efforts,\u201d said Miller. \u201cIt really is a team effort.\u201d\u003C\/p\u003E\u003Cp\u003EFor the GTRI researchers, the project provides not only an interesting technical challenge \u2013 but also a deeper reward.\u003C\/p\u003E\u003Cp\u003E\u201cWhat we are doing is certainly interesting technical work, but the results go out into the field to save the lives of our soldiers and allow them to return home to their families,\u201d said Miller. \u201cAll of us enjoy doing challenging engineering work, but when we stand back and look at what\u2019s really happening here, saving lives is the rewarding part.\u201d\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EResearch News\u003C\/strong\u003E\u003Cbr
