Navigation-Grade MEMS Inertial Measurement Unit (IMU)

Abstract

(U)The Navigation-Grade MEMS Inertial Measurement Unit (IMU) program developed micro-scale accelerometers and gyros with navigation-grade performance that use only milli-watts of power. The program transcended traditional single mass-spring methods for navigation sensing and explored alternative approaches, such as multiple, interconnected mass-spring systems, micro-levitated spinning structures, micro-optical readout mechanisms, atomic interferometric readout mechanisms, and fluidic contortions. This program has transitioned to industrial performers for developing wearable inertial measurement units (IMUs) for dismounted warfighters capable of GPS-denied navigation for lengthy periods; small IMUs for unmanned air and underwater vehicles, and for guidance of small, long-range munitions.
