摘要： Inertial measurement units (IMUs) and methods with adaptations to eliminate or minimize sensor error, offset, or bias shift. More particularly, such IMUs and methods for gun-fired projectiles and particularly adapted to accurately measure forces and to prevent or minimize the error, offset, or bias shift associated with events exhibiting high g shock, and/or high levels of vibration, and/or rotation. Even more particularly, such IMUs and methods utilizing novel IMU packaging adapted to prevent or minimize sensor error, offset, or bias shift, and recalibration adaptations and methods adapted to correct or reset the error, offset, or bias shift from such an event. Ultimately relates to IMUs that are adapted to provide accurate measurements prior to, during and after such event, and to provide continuous accurate measurements during flight of gun-fired projectiles.

摘要： The present invention relates to a sensor suite comprising at least one sensor. More particularly, the present invention relates to a sensor suite for measuring absolute and/or relative position, location and orientation of an object on or in which the sensor suite is employed. The present invention further relates to improved, novel sensor types for use in the sensor suite. More particularly, the present invention relates to an improved, novel magnetometer that is self-calibrating and scalable. Still more particularly, the present invention relates to such a magnetometer that is miniaturized. Further embodiments of the present invention relate 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).

摘要： 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.

摘要： Presented herein are systems and methods using inertial measurement units (IMUs) 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), and for such location and guidance being provided to projectiles, munitions, or rounds that are released, fired, or deployed from vehicles or weapons systems. More particularly, this disclosure 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. This further relates to 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.
