Abstract
Generally, implementations of the present invention include devices, systems, and methods for tracking intermittent motion. Such systems can be used to calibrate inertial measurement units (IMUs), which can be used to obtain acceleration, linear and angular velocities, orientation, and position of a moving body. Such systems also can be used to account and compensate for errors and imperfections present in an IMU prior to and during operation.
