Multi-imu guidance measurement and control system with handshake capability to refine guidance control in response to changing conditions

Abstract

Systems and methods for providing location and guidance, and more particularly for providing location and guidance in environments where global position systems (GPS) are unavailable or unreliable (GPS denied and/or degraded environments) utilizing inertial measurement units IMUs to provide such location and guidance. A series of low-accuracy or low-resolution IMUs, in combination, are utilized to provide high-accuracy or high-resolution location and guidance results along with an electronics-control system for handing off control of the measurement and guidance of a body in flight between groups or subgroups of IMUs to alternate between high dynamic range/lower resolution and lower dynamic range/higher resolution measurement and guidance as the environment dictates.
