Abstract
Systems and methods for providing location and guidance are herein described, 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). The systems and methods herein utilize inertial measurement units (IMUs) to provide such location and guidance. More particularly, the systems and methods herein utilize a series of low-accuracy or low-resolution IMUs, in combination, to provide high-accuracy or high-resolution location and guidance results.
