An Integrated GPS/Micro-Mechanical IMU for 5 Navy Projectiles

John R. Dowdle and Karl W. Flueckiger

Abstract:	The Extended Range Guided Munition Demonstration Program is a joint technical effort between Draper laboratory and the Naval Surface Warfare Center, Dahlgren Division, with programmatic responsibility residing in the Naval Surface Fire Support Program Office, Naval Sea Systems Command. The program will culminate in four flight tests beginning in the Summer CE 1996 that demonstrate extended range and improved s:curacy over conventional Navy 5” projectiles. This paper describes the design, operation and critical performance issues of the ERGM Demonstration GPSMMIMU, which is the guidance system for the Navy’s 5” ERGM Demonstration Round. This guidance system combines GPS position data with micro- mechanical inertial sensor measurements to produce the navigation solution, and uses the navigation data with a prespecitied aimpoint location to generate guidance commands. In addition to the GPS receiver and the Micro-Mechanical Inertial Sensor Assembly, the system includes a g-hardened reference oscillator, the guidance and navigation electronics, and the power conversion electronics, all packaged in an 8 lbr cylindrical volume 8.4 inches long with a diameter of 4 inches.
