XIMIR (Extreme-SWAP IMU for Missiles and Interceptors: Rad-hard), is a co-planar IMU development program that combines two navigation-grade inertial sensors being independently developed under separate funding with a novel packaging solution for shock, vibration and temperature immunity. Rad-hard ASICs for the inertial sensors are part of the 3-Phase effort, yeilding a compact IMU form factor of less than 10 cc while consuming less than 1 W including temperature control for low in-run bias stability. The inertial sensors are highly compatible for co-packaging. They have the same form factor, are made from identical materials, require similar support electronics, and provide a full 6-DOF measurement without orthogonal mounting of sensors. As a result, cross-axis alignment is sub micro-radian.
