Patrick Grates is a graduate student at Arizona State University working on a PhD in Systems Engineering and studying Micro Electronic Mechanical Systems (MEMS) based Inertial Instruments for navigation purposes. He teaches Statics, Dynamics, and MATLAB at South Mountain Community College (SMCC) as an adjunct instructor after working 36 years in the aerospace industry. While working in intermediate and depot level testing of Standard Missile system in 1987, Mr. Grates taught Missile Operations classes at the Naval Surface Warfare Center to defense contractors and weapon station personnel. This was an 8-hour per day one-week class that described how the missile worked, how it interfaced with the fire control system, and how it was tested. This course was offered twice a year at various locations throughout the United States. Starting in January 2018, Mr. Grates began teaching at South Mountain Community College focusing on engineering classes. Mr. Grates worked in the development, procurement, and sustainment of precision Inertial Navigation Systems (INSs). Development focused on Focused Fiber Optic Gyro (FOG) based INSs, and sustainment on spinning mass based INS. Research into advanced mechanization techniques that minimize error and prevent gimbal lock. In-service INS supports Ohio Class submarine with Trident II strategic missile system. Mr. Grates also worked in Integration and Test of Tactical Shipboard Weapon Systems. Ground testing the missile and flight testing tactical missiles - scenario definition, implementing test range upgrades, determining target systems requirements, writing flight test plans and procedures, and reporting results to the program sponsor. Chaired and participated in Test and Evaluation integrated product teams and related project-working groups.
