We've moved! Follow Us on the DCSCorp LinkedIn. IST became a DCS company in 2012. Since that time, the two companies have worked and grown together—leveraging cross-corporate capabilities including a complementary portfolio of aerospace and defense technologies. Now operating as one united DCS, the integrated organizations will continue providing excellence in program support across key technical areas including human-machine interface, modeling & simulation frameworks, weapon systems effectiveness analysis, simulation-based research and development, human-autonomy systems, cognitive neuroscience, aerospace physiology, biodynamics research, intel production, and sensor modeling simulation and analysis. Our customers and partners are assured that the DCS IST Sector will continue to provide the same people, same expertise, and same quality of service that become been synonymous with the IST brand.
