Formerly known as Alphatech, a 1979 spin-off from MIT, the firm was acquired by BAE Systems in 2004. Now doing busness as Advanced Information Technologies (AIT), the firm develops advanced technologies and software solutions that bridge the gap between fundamental research and its operational deployment. AIT staff work at the cutting edge of technology to develop, transition and exploit breakthroughs and innovations in signal and image processing, networking and communications, tracking and sensor management, computational social science, knowledge discovery and data mining, fusion and information integration, cognitive and neural systems, battle management/command and control, decision aids/intelligent systems, information assurance and security, distributed systems and advanced computing. Alphatech had specialized in artificial intelligence, computer vision, modeling and simulation, tracking, data fusion, resource allocation, strategic decision aids, and signal processing. With early strong ties to MIT, ALPHATECH are experts in information processing, software development, and systems engineering. The professional staff have backgrounds in engineering, mathematics, operations research, computer science and physics. The firm maintains a major in-house research programs and extensive collaboration with the academic community addressing research, modeling, simulation, algorithm development, software development, software testing, technical consulting, and systems integration.
