Abstract
The present invention relates to 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). The present invention further relates to systems and methods for using inertial measurement units IMUs to provide location and guidance. More particularly, the present invention relates to the use of a series of low-accuracy or low-resolution IMUs, in combination, to provide high-accuracy or high-resolution location and guidance results.
