MSSA's single-chip Integrated MEMS IMU will be substantially smaller and less expensive, and will enable more highly-integrated applications than are possible with other MEMS IMUs. The principal military applications of MEMS IMUs are for interceptors and for precision-guided munitions, especially spinning munitions. Other military and commercial applications for MEMS IMUs are for the stabilization and GN&C of vehicles; for the stabilization and GN&C of small UAVs and for stabilization of UAV-borne sensors, seekers and cameras, (including Homeland Security and police operations); lower-cost IMUs for air, land and water vehicle navigation, with or without GPS-aiding; Personal Navigation for warfighters and civilian "first responders" such as fire-fighters; robotic stabilization and GN&C; precision motion tracking for portable/wearable systems (helmets & headsets); precision pointing and tracking for satellites, antennas and telescopes; and bore-hole measurement systems. MSSA's MEMS IMU Sensor Chip enables modular and programmable guidance & navigation systems with significantly reduced mass and cost for low-cost small spacecraft, microsatellites and nanosatellites. A MEMS IMU integrated with a reaction wheel enables both the measure of spin rate as well as the determination of attitude when three wheels are used. The applications are generally pointing and tracking.
