Silicon Inertial and GPS Guidance for Gun Launched Munitions

Mahendra Singh, John Fraysee, Sanjai Kohli

Abstract:	A gun launched Inertial-GPS receiver program was initiated by NSWC Dahlgren. An inertial sensor is being developed under this program which will withstand the high shock and rotational g’s ofthese munitions. The sensor is a micromachined silicon sensor, in a multisensor conftguration, required to meet the aggressive cost target of less than $3,000. The paper describes this inertial sensor and GPSRnertial architecture for minimized cost. A test program for the silicon sensor is described. System integration issues pertaining to “up fmding” or leveling ofthe reference Same in zero g field are also discussed. Finally, the packaging plan for this system is presented where MCMs with flipped chip bonded components with encapsulation are used to survive the 30,000 g set back shock.
