Test & Evaluation (T&E) is one of GST’s core competencies and most diversified technical areas. GST supports all aspects of testing; from Master Test Plans through developmental, operational, and certification testing of new systems; to verification and validation of work done by other contractors. Since 1993, we have supported Test & Evaluation for all security equipment deployed by the TSA, including Explosives Trace Detection equipment, threat image projection, bottle screening systems, metal detector portals, and Advanced Technology equipment

GST produces various commercial, military and homemade explosive simulants for DHS and other governmental agencies. These simulants are safe, inert material, but when examined by an explosive detection system, they mimic the properties of the real explosive.
