GSE Systems, Inc. develops and markets software-based simulation and training products to nuclear, oil, and gas electricity generators, and the chemical process industries. It also sells software for monitoring and optimizing plant and signal analysis to the power industry. GSE Systems was established in 1994 from three simulation companies that came together. They were part of an original heritage from Singer-Link where they were involved in high-intensity simulation applications such as flight simulators. Since 1994 the company has grown through acquisitions. The primary businesses continue to be process control focused in the chemical, pharmaceutical and food industry, and simulation, which is also focused on fossil and nuclear simulation. GSE Systems is headquartered in suburban Baltimore, Maryland. Global operations are conducted from offices in Columbia, Ft. Worth, and Beijing.
